- 1. PURPOSE: What does this program do and what is it all about?
- ===============================================================
- In short: numerical calculations, data processing,
- graph generating, viewing, printing,
- in-line calculator.
-
- Frequently experimentally measured data is a set of
- N points written in a text file in two columns:
- X1 Y1
- X2 Y2
- etc.,
-
- which represents a real function Y of a real variable X. Let us call this
- object "a graph". The program "calc" allows one to do arithmetic and algebraic
- operations on graphs and real numbers: add graph+graph, convolute, etc. All
- operations are NUMERICAL. Calc also knows fitting, smoothing, interpolation,
- integrals, standard and some special functions, and much more.
-
- Calc allows one to plot on a screen (EGA/VGA) and print on a PostScript
- Printer.
-
- Calc works under DOS. It takes commands from a command line. Language is a
- simple algebra:
-
- calc a = b+sin(x)^3 etc.
-
- where b,x and a are graphs/numbers (i.e. names of the files containing graphs)
- in the sense described above.
-
- One can write programs doing numerical calculations and/or manipulating
- experimental data in batch files.
-
- 2. INSTALLATION
- ===============
-
- Usually, a distributed version is compiled for 286 processor with a math
- co-processor & EGA/VGA monitor and works under DOS. If your computer is
- different, (no math co-processor, etc.) a custom compiled version is available
- upon request.
-
- How to find out, what version do you have?
- If your computer does not have a math co-processor, and calc gives obviously
- wrong answers like
- calc 1+2
- 1+2 = 10^24
- you need a version with float arithmetic emulation.
-
- To install calc, put calc.exe in the path BEFORE WINDOWS.
- Example:
- take a look into autoexec.bat:
- if your path is
- path=C:\WINDOWS;C:DOS;C:\TOOLS;
- make it:
- path=C:\TOOLS;C:\WINDOWS;C:DOS;
- copy calc.exe into C:\TOOLS and reboot your computer.
-
- 3. STATUS OF THE PROGRAM & DISTRIBUTION
- =======================================
- This program is a shareware. You can copy and distribute it freely as long
- as you distribute the whole original package which includes readme.txt file
- and all example files (*.bat).
-
- Disclaimer:
- This program is provided "as is" without warranty of any kind. In no event
- shall author be liable for any loss of profits, loss of business, loss of use
- or data, interruption of business, or for indirect, special, incidental, or
- consequential damages of any kind, arising from any error in this program.
-
- 4. HELP or How to Learn It
- ==========================
- There are several batch files (*.bat) coming with it.
- View them and run them.
- The file helps.bat shows how to use help commands of calc.
