CMPCALC3 INSTRUCTIONS 09/15/88 (1) E 1. -1Introduction-0F CMPCALC3 converts your PC temporarily into a progammable calculator for complex numbers, having real and imaginary parts. It uses reverse Polish notation (RPN), like Hewlett-Packard calculators.Complex numbers and functions become as easy to handle as real ones. In addition to addition,subtraction,multiplication and division, (+,-,*, and /), CMPCALC3 has complex exponential, complex logarithmic, complex trignometric, complex hyperbolic, and a complex square root function. It also has 9 labeled storage areas, which are shown on the screen, and 41 numbered storage areas, which are not. All stores may be saved in a .CLC file. A labeled store whose label begins with POL will display its data in polar form. CMPCALC3 can be used very efficently for repetitive calculations since it can memorize programs of up to 50 commands, and save the program in a .CLC file. CMPCALC3 is copyrighted by Soft Engineering Inc., and a cost free license, for Enon-commercial use onlyF is granted to individuals in the general public. (See last chapter.) CMPCALC3 has a much more powerful big brother, CMPCALC4, with 500 command programs, reentrant programs, the ability to use several programs at once, increased functions, and telephone support. It may be purchased for only $49.90. (See last chapter.) COPYRIGHT 1988 UDH ENTERPRISES INC. CMPCALC3 INSTRUCTIONS 09/15/88 (2) E 2. -1Getting Started-0F With CMPCALC3.EXE on your active disk/directory type CMPCALC3. After the title screen you will see: ENTER CMPLX NO.OR ORDER ("H" FOR HELP) and a blank screen. Pressing H (or h) will show three help screens summarizing the information in these instructions. (Press H anytime you wish when you see the instruction, nothing will be lost and the original display will be restored immediately after the help screens.) For now lets try entering a complex number, say 2+3i. Enter 2<blank>3 and press <Enter>. You should see: ENTER CMPLX NO.OR ORDER ("H" FOR HELP) 2.0000000000E+00 3.0000000000E+00 You can enter decimal numbers as well as integers. Now enter 2.5<blank>3.5. You should see: ENTER CMPLX NO.OR ORDER ("H" FOR HELP) 2.5000000000E+00 3.5000000000E+00 2.0000000000E+00 3.0000000000E+00 You can also enter numbers in scientific notation (As you see thats how they are displayed anyway). Enter 5E-1<blank>2E2. You should see: ENTER CMPLX NO.OR ORDER ("H" FOR HELP) 5.0000000000E-01 2.0000000000E+02 2.5000000000E+00 3.5000000000E+00 2.0000000000E+00 3.0000000000E+00 Notice how the last number you entered always goes to the top of the stack with earlier numbers pushed down? Thats characteristic of RPN calculators. COPYRIGHT 1988 UDH ENTERPRISES INC. CMPCALC3 INSTRUCTIONS 09/15/88 (3) Lets do something with these numbers. With RPN calculators the top of the stack is always one of the operands, the other (if there is another) is the number immediately below in the stack. Now enter a + to add the two top numbers. You should now see: ENTER CMPLX NO.OR ORDER ("H" FOR HELP) 3.0000000000E+00 2.0350000000E+02 2.0000000000E+00 3.0000000000E+00 Notice that the first two numbers on the stack have vanished, and the first number on the stack is now their sum. The third number on the stack is unchanged (but is now the second number.) Had there been more numbers on the stack they too would be unchanged. We can also subtract the top number on the stack from the second by entering -. This yields: ENTER CMPLX NO.OR ORDER ("H" FOR HELP) -1.0000000000E+00-2.0050000000E+02 Notice how the negative numbers are shown. Lets get rid of this number and enter new ones for illustrating multiplication and division. Entering CLR will clear the top number from the stack, ACLR will clear the entire stack. Since our current stack is only one number high we can use either. Do so restoring your screen to: ENTER CMPLX NO.OR ORDER ("H" FOR HELP) Now lets enter 1<blank>2 and the 2<blank>1 giving: ENTER CMPLX NO.OR ORDER ("H" FOR HELP) 2.0000000000E+00 1.0000000000E+00 1.0000000000E+00 2.0000000000E+00 To multiply these we enter * yielding: COPYRIGHT 1988 UDH ENTERPRISES INC. CMPCALC3 INSTRUCTIONS 09/15/88 (4) ENTER CMPLX NO.OR ORDER ("H" FOR HELP) 0.0000000000E+00 5.0000000000E+00 Lets try some unary functions, ones involving only one number (always the one at the top of the stack). To take the square root of 5i (the number now on top of the stack) enter SQRT yielding: ENTER CMPLX NO.OR ORDER ("H" FOR HELP) 1.5811388301E+00 1.5811388301E+00 Lets check this result. Duplicate the number on top of the stack by entering DUP. You should now have: ENTER CMPLX NO.OR ORDER ("H" FOR HELP) 1.5811388301E+00 1.5811388301E+00 1.5811388301E+00 1.5811388301E+00 Now multiply them together by entering *. You should see: ENTER CMPLX NO.OR ORDER ("H" FOR HELP) 7.2759576142E-12 5.0000000000E+00 Not surprisingly we're (almost) back where we started. Inversion (1/) inverts the number on top of the stack. Try it by entering 1/ and getting: ENTER CMPLX NO.OR ORDER ("H" FOR HELP) 2.9103830457E-13-2.0000000000E-01 Of course entering another 1/ restores the 5i. There is one more elementary binary function, division (/) which divides the second number in the stack by the number on top of the stack,and, as always in RPN calculators, removes the operands and places the result on top of the stack. Clear the stack, enter 1<blank>2 and 2<blank>1, and then enter /. You should have: COPYRIGHT 1988 UDH ENTERPRISES INC. CMPCALC3 INSTRUCTIONS 09/15/88 (5) ENTER CMPLX NO.OR ORDER ("H" FOR HELP) 8.0000000000E-01 6.0000000000E-01 I'm getting off here. You now have all you need to use CMPCALC3 as a 4 function complex calculator. Play around till you feel comfortable with it. When you're finished enter FIN to return to DOS. See you next chapter where we'll learn about storage areas, and even do something (somewhat) useful. E 3. -1Storage Areas-0F CMPCALC3 provides 50 storage areas where you can store complex numbers, either entered or the result of calculations, and from which you can recall them for further calculations. 9 of these areas (the labelled stores) appear on the screen, and can be labelled by you, as anything you wish, as long as it starts with a letter and has no more than 10 characters. Numbers may be entered into the labelled storage areas from the top of the stack, (EallF operations use the top of the stack), by entering STO<blank><LABEL> where <LABEL> is any sequence of 10 characters or less, beginning with a letter. Try it. Enter 2<blank>3 and then STO<blank>STORE1. You should see: ENTER CMPLX NO.OR ORDER ("H" FOR HELP) 2.0000000000E+00 3.0000000000E+00 < 20 Blank Lines> 2.0000000000E+00 3.0000000000E+00 STORE1 Lets store another number, this time the square of 2+3i in another labelled area we'll call STORE2. Remember how to square a number? Enter DUP, then *, and then STO STORE2. You should now have: ENTER CMPLX NO.OR ORDER ("H" FOR HELP) -5.0000000000E+00 1.2000000000E+01 < 16 Blank Lines> 2.0000000000E+00 3.0000000000E+00 STORE1 -5.0000000000E+00 1.2000000000E+01 STORE2 COPYRIGHT 1988 UDH ENTERPRISES INC. CMPCALC3 INSTRUCTIONS 09/15/88 (6) Let us build a table of powers of 2+3i, putting the 3rd power in STORE3, the 4th in STORE4, and so forth. (I only promised you that I'ld show you something -1somewhat-0 useful in this chapter. The applications get more practical as we go on further.) We now have the square of 2+3i on top of the stack, and its first power in STORE1. To obtain the 3rd power recall STORE1 by entering REC<blank>STORE1, and then entering *, and STO STORE3. Repeat the procedure till youve built a table of 9 entries: ENTER CMPLX NO.OR ORDER ("H" FOR HELP) -8.6158000000E+04 5.6403000000E+04 < 12 Blank Lines> 2.0000000000E+00 3.0000000000E+00 STORE1 -5.0000000000E+00 1.2000000000E+01 STORE2 -4.6000000000E+01 9.0000000000E+00 STORE3 -1.1900000000E+02-1.2000000000E+02 STORE4 1.2200000000E+02-5.9700000000E+02 STORE5 2.0350000000E+03-8.2800000000E+02 STORE6 6.5540000000E+03 4.4490000000E+03 STORE7 -2.3900000000E+02 2.8560000000E+04 STORE8 -8.6158000000E+04 5.6403000000E+04 STORE9 If you try to go beyond the 9th labelled store you will get a !!STORE FULL!! message and the attempted storage will be rejected. Try it, nothing will be hurt. You can release a labelled storage area by entering 0<blank>0 into it, (from the top of the stack, of course). You are then free to reuse it with the same or a different label. Try it. There are also 41 numbered storage areas, numbered 10 to 50, which do not appear on the screen. Initially each one has 0+0i in store, (See for yourself, Enter REC 33 for example.), but can be loaded ,like the labelled stores, from the top of the stack. For example try loading store 38 with 3+8i by entering 3<blank>8, and then STO 38. You wont see the store on your screen, but it's there and can be brought to the top of the stack, at any time, by entering REC 38. The numbered stores are handy for storing constants in formulas, while the labelled stores are good for holding variable parameters and intermediate or final results. (We'll illustrate this use in the next chapter.) You can COPYRIGHT 1988 UDH ENTERPRISES INC. CMPCALC3 INSTRUCTIONS 09/15/88 (7) save all stores and labels in a disk file by entering SAV <yourname>, where <yourname> is any legal filename without extension. (CMPCALC3 will add .CLC.) You're on your own for a while now. Play around and get comfortable. I'll be back next chapter and show you how to write and save programs. E 4. -1Programs - writing and memorizing-0F Lets do something worthwhile, set up a program for solving quadratic equations with complex coefficents. You remember the formula from high school algebra: The solution of A*X^2+B*X+C = 0 is: X1 = (-B+D)/(2*A) AND X2 = (-B-D)/(2*A) WHERE D = SQRT(B *B-4*A*C) In high school A,B, and C were always real, while X1 and X2 could be complex. The formula works just as well with complex coefficents. We'll start with A=B=C=1, memorize the steps we used to solve the formula, and then solve it automatically with other coefficents. We start by entering MEM to enter the memorizing mode. The heading line now becomes: >>MEMORIZING<< ENTER CMPLX NO.OR ORDER ("H" FOR HELP) Enter orders as on following table: Enter Why ACLR Clear Stack CLS Clear Stores 1 Entering value of A. (If entry real drop imag) STO A Store Value in A 1 Entering value of B STO B Store Value in B 1 Entering Value of C STO C Store Value in C REC B B now on top of stack COPYRIGHT 1988 UDH ENTERPRISES INC.

CMPCALC3 INSTRUCTIONS 09/15/88 (9) That was some work that we wont have to go thru again, save it by entering SAV QUAD. The program is then saved in file QUAD.CLC and can be recalled at anytime you're using CMPCALC3 by entering LOAD QUAD and then RPT. Since the program is already in memory we can recall it now by simply entering RPT.Lets do so. The display clears and we see: !!AUTO!! ENTER CMPLX NO. STEP 3 This tells us that we are running a memorized program which has stopped at step 3 for data input. Here is where we entered the value for A; lets try a new value, say 1+2i; enter 1 2. The value we entered now appears, stored and displayed with label A. The heading now tells us that its at step 5. It's waiting for B, give it 2+3i. Now, at step 7 give it 3+4i for C. In a flash we get: ENTER CMPLX NO.OR ORDER ("H" FOR HELP) < 14 Blank Lines> 2.0000000000E+00 3.0000000000E+00 B 3.0000000000E+00 4.0000000000E+00 C 4.8355330807E+00-2.8952340448E+00 D -8.9549350089E-01-1.1566300206E+00 X1 -7.0450649911E-01 1.3566300206E+00 X2 1.0000000000E+00 2.0000000000E+00 A Check the result, right from the present display by direct substitution in the original equation. You can do it, it's easy. The QUAD program is worth some study, note how I used DUP and + to avoid entering 2 and 4, thereby eliminating any need for the memorized program to stop for their entry. Alternatively I could have loaded 2 into a numbered store and used it in the program by REC its store. Such a technique would be necessary if complicated fixed parameters were involved. Play with the Quad program a while, trying various A,B,Cs, then try your hand at modifying or improving it. You should COPYRIGHT 1988 UDH ENTERPRISES INC. CMPCALC3 INSTRUCTIONS 09/15/88 (10) be able to somewhat better it. It was designed for transparency, not efficency. A command you'll find useful is SWI n, where n is any integer >1 and < the depth of the stack. It brings the number at depth n to the top of the stack, and moves the number that was on top to depth n. See you next chapter. E 5. -1Interlude - Program EDCLC-0F Sometimes I forget the details of a program I've saved in a .CLC file. Occasionally I even make mistakes in the program or data entered. You may have similar problems. If so the program in file EDCLC.EXE will prove handy. To call it up just enter EDCLC from DOS. It will ask you for the name of the .CLC file you want to work on, then permit you to conveniently inspect and modify it. Theres no need to go into detail here, the program is self instructing. Call it up and play with QUAD. COPYRIGHT 1988 UDH ENTERPRISES INC. CMPCALC3 INSTRUCTIONS 09/15/88 (11) E 6. -1A More Substantial Program-0F Lets do some work. Below is the schematic of a 1000 ohm, 1000 hz cutoff, m = 0.6, image derived pi section lo pass filter. 0.191 H 1E-6 Ohms Vin ----------------((((((((((----/\/\/\---------------------Vout I L R I I I I I C2 I I I--------I I---------------I I I I I 1.19E-7 Fds.

(It's a lousy filter as you'll soon see, but is a passable example of how to put a real circuit on the calculator.) First we'll load up the numbered stores. From CMPCALC3 enter: PI, then DUP, then +, then STO 10, loading store 10 with 2 pi, which we will need later for converting frequency into radians per second. We next enter: 1000, then STO 11, saving Load resistance. 0 0.191, then STO 12, saving L inductance. 0 9.5E-8, then STO 13, saving C1 capacitance. 0 1.19e-7, then STO 14, saving C2 capacitance. 0 9.5E-8, then STO 15, saving C3 capacitance. (Inductance is entered as an imaginary value because, when multiplied by angular frequency it becomes an imaginary impedance. Capacitance is entered as an imaginary value because, when multiplied by angular frequency it becomes an imaginary conductance. Alternatively, and better, we could have entered inductance and capacitance as real, and frequency as imaginary.). COPYRIGHT 1988 UDH ENTERPRISES INC. CMPCALC3 INSTRUCTIONS 09/15/88 (12) We next enter the L resistance as a displayed labeled store by entering 1E-6, and then STO R. (Initially we're using a very low value to simulate the lossless case. If we used 0 then store R would not be displayed and might be overwritten.) Finally we enter the program: We start by entering MEM to enter the memorizing mode.

The program, like the filter leaves much to be desired. It was written for easy understanding, not efficent use. As you get more familiar with CMPCALC3 you'll find that you will make much less use of stores for intermediate results, instead keeping them on the stack. This saves steps and makes for a cleaner display. A more efficent program for the same filter is: COPYRIGHT 1988 UDH ENTERPRISES INC.

CMPCALC3 INSTRUCTIONS 09/15/88 (19) E 7. -1Advanced Functions-0F We have already used one of the functions in QUAD, SQRT. When SQRT is entered the value on top of the stack is replaced by its square root, a real number if the original value was real and positive, an imaginary or complex one otherwise. SQRT is a bivalued function, besides the value returned by CMPCALC3, the same value times -1 is equally the SQRT function. In certain procedures, (such as QUAD), this must be allowed for. The complex exponential function is obtained by entering EXP which replaces the value on top of the stack with e raised to that value. The exponential function is single valued. Two complex trignometric functions are furnished SIN and COS. If the complex tangent is needed it can be obtained by entering in sequence DUP, SIN, SWAP, COS, /. The trignometric functions are single valued. Two complex hyperbolic functions are furnished SINH and COSH. If the complex hyperbolic tangent is needed it can be obtained by entering in sequence DUP, SINH, SWAP, COSH, /. The hyperbolic functions are single valued. The complex logarithmic function is obtained by entering LN which replaces the value on top of the stack with its complex logarithm. The logarithmic function is multi-valued, besides the value returned by CMPCALC3, the same value +2*n*pi, where n is any positive or negative integer, is equally the SQRT function. In certain procedures this must be allowed for. COPYRIGHT 1988 UDH ENTERPRISES INC.

In that case use CMPCLCG3.EXE instead of CMPCALC3.EXE, (and EDCLCG3.EXE instead of EDCLC3.EXE). There will be three differences from the description in the Manual: (1) The program will be called up by typing CMPCLCG3, instead of CMPCALC3. (2) The line: ENTER CMPLX NO.OR ORDER ("H" FOR HELP) will appear at the bottom of the screen, instead of at the top. (3) The display will change by scrolling, much more slowly than CMPCALC3. A disk with CMPCLCG3.EXE and EDCLCG3.EXE may be obtained by sending $15.00 with your order to: UDH Enterprises Inc 1000 E.William St., Suite 100 Carson City, Nevada 89701 Mail order only, prepaid only. You may instead want to order the much superior program CMPCALC4 which comes with a version for incompatible machines on the same disc. It may be ordered for only $39.95 from the address above, or by phone, using your MasterCard or Visa, by calling 1-800-888-7070, ext.103.
