Developer's Description

By Mark Widholm

MathPad is a general purpose graphing scientific calculator. It uses a text window rather than simulating buttons on a hand held calculator. Formulas can be entered directly and different values can be plugged in for easy "what if" calculating. In addition to being a handy little calculator, MathPad can also take on larger problems. Simple plotting allows quick visualization of results. General purpose arrays allow calculations involving vectors, complex numbers, matrix algebra etc. 2D arrays can be displayed as grayscale or color images. Several examples are included showing such things as equation solving, curve fitting, vector calculations and numerical solution of differential equations.

Full Specifications

What's new in version 3.0.4

Rename old MathPad documents to .mp. OS 10.7 ignores the mac "creator" code so it is impossible for the new application to determine ownership of all old MathPad documents.
Sadly the enter key is gone on new keyboards and even if you use an old keyboard, OS 10.7 re-maps enter to return.
The old XFun plugins do not work under OS 10.7. Many of the former XFuns are now built in as Optional Functions and are available simply by enabling them in the Functions window.
Unless you only used source file relative includes, you will need to modify your include file path names or move your include files. The new base directory for includes is: ~/Documents/MathPad/.
MathPad now uses rtf instead of plain text as its default document format. It will read old MathPad documents and convert the old preference information. By default it will convert the document to rtf and when you close it, it will save it with a .mp extension.
If you are converting old documents they will keep most of thier preferences.
There are minor changes in the menus but hopefully they are fairly obvious ones.
Arbitrary labels can not be pasted directly onto the plot. You can still put arbitrary labels anywhere on the plot but the text must appear as a label or slabel statement in the text source file.
Old documents that had graphics pasted into the text or as a plot overlay will lose that information. If the old MathPad document is your only copy of the graphic, you may want to see if you can retrieve it before converting the document to version 3.04.
Old data files can be used as-is except for FLT8 format. The FLT8 format is the native PPC double and is not supported. There is now a corresponding format DBL8 which is the native intel double and can be used for new files.
