-- MathPad is a general purpose graphing scientific calculator. It uses a text window rather than simulating buttons on a hand held calculator. This live scratchpad interface allows you to see and edit your entire calculation.
---------- Installation -----------------------
-- MathPad 2.4 runs on any Mac with a 68020 or better and system 7.
-- No special installation is required. MathPad can be run directly from the distribution folder. It does not require or create any auxiliary files. If you are impatient to get started, go ahead and double click on MathPad. Built-in help is available via the Help item under the File menu.
------- installing on PowerPC Macs
-- The 68K version of MathPad will run on PowerPCs but for those who want more speed, a native PowerPC version is included. The archive file "MathPadPPC.sea" contains the PowerPC application. Double click on this file to extract. After extracting the application "MathPadPPC" you can delete the archive. If you plan on using MathPad only on PowerPC Macs, you can also throw away the 68K "MathPad" application and keep only the "MathPadPPC" application.
-- If you do not have a PowerPC, you can throw away "MathPadPPC.sea".
---------- Upgrading to version 2.4 ----------------
-- See the file "What's New" for a details on how to use new features.
-- Existing version 2.3 documents should work fine with version 2.4.
-- The words "on","off" and "Radians" are now reserved. These could conflict with existing user names.
-- A 68020 or better and system 7 are now required. If anyone still needs a 68000 or system 6 version, contact me.
---------- Using MathPad --------------------
-- MathPad may be used as a calculator simply by typing in numbers and operators. When the ENTER key is hit, each line is evaluated and the results are inserted into the text.
2*(3+4):14.000
-- MathPad inserts the ":" and the result "14.0". A status line at the bottom of the window will show a "√" to indicate that evaluation is complete. If any problems are encountered, they will be reported in the status line and the cursor will be moved to the problem in the text. You can edit and reevaluate the text at any time. The RETURN key simply terminates a line. It does not cause any evaluation. The ENTER key is on the numeric keypad (or next to the space bar on PowerBook keyboards).
-- MathPad can do much more than act as a simple calculator. The "Documentation" folder contains more information about MathPad's capabilities.
-- The "Examples" folder contains examples and utility functions. These examples show how to implement such things as equation solving, curve fitting, vector calculations and numerical solutions of differential equations.
-- The "XFuns" folder contains various extensions that can be added to Mathpad's function menu by moving them into MathPad's folder. (If MathPad is already running you must quit and restart it to see the new XFun). This distribution includes XFuns for linear fitting, FFT signal processing, 3D plotting etc.
-- An "XFun kit" is provided to help programmers create their own XFuns.
-- Once you have decided how you want to set things up, it is best to create a separate folder for MathPad. You can then extend MathPad's capabilities by putting your favorite XFun and include files in MathPad's folder. Adding XFuns will increase MathPad's memory needs. If you are using advanced features you may need to use the Finder's Get Info box to increase MathPad's memory size. See the documentation file "Customizing" for more details.
-- The distribution folder contains the XFun file "intro help". This adds a few simple examples to the help menu and may be useful for beginning users. This file can be removed to save a little memory and to unclutter the help menu.
-- Check out the MathPad web page <http://pubpages.unh.edu/~whd/MathPad/> for more examples and XFuns.
