Mathomatic

Mathomatic is a general purpose and highly portable symbolic math program that allows you to solve, combine, simplify, differentiate, compare and integrate algebraic equations.

Mathomatic can do modular, complex number and polynomial arithmetic.

Features:

• Solve equations,
• Completely simplify equations,
• Do calculus transformations,
• Do sensitivity and finite series analysis,
• Do complex number and polynomial arithmetic,
• Generate efficient C or Java code,
• And more!

What is new in this release:

• Allow use of editline library in Mathomatic, because somehow use of GPL libraries in LGPL code is not allowed, and GNU readline is GPL. I am so confused about this Debian bug#687063: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=687063 Based on the bug report's information sources, it appears he is saying the truth about this license issue, so I will have to upload new versions of Mathomatic with editline instead of readline to Debian. The only noticeable difference should be it doesn't save the history between Mathomatic sessions. I will comply with all that request it, though most distributions do not include editline, which has no major licensing restrictions. Readline is still perfectly usable and good as before, you just have to link it in yourself.

What is new in version 16.0.0:

• Allow an ASCII string after the "set save" command, to save only that string in ~/.mathomaticrc, so that string, which should be set options, is for every Mathomatic session to start with. For example, "set save bold color" will start out Mathomatic in bold color mode every time. Enter "set no save" to remove. "set save" by itself saves all of the current set options for every future session.

What is new in version 15.8.5:

• Added detection of the terminal's ANSI color availability, when readline is enabled.

What is new in version 15.8.4:

• Added detection of the terminal's ANSI color availability, when readline is enabled.

What is new in version 15.8.3:

• Added simplifying trig identities to the tests.
• Discovered "solve 0" doesn't work anymore, use "solve for 0" instead. "solve 0" will be fixed and enhanced shortly.

What is new in version 15.8.2:

• A change to the matho script makes GNU m4 no longer quiet about any warnings or errors, when running m4 Mathomatic.

What is new in version 15.8.1:

• Some important missing documentation has been included, starting in this release, to take the guesswork out of using Mathomatic.
• The makefiles and modulus simplification have been fixed.

What is new in version 15.8.0:

• It fixes simplification of division by expressions with imaginary numbers in them.
• This allows complex exponential expressions like the tan(x) and cot(x) expansions to simplify nicely now with m4 Mathomatic.
• This was a bug only in the previous version of Mathomatic (15.7.3).
• A few other minor improvements have been made.

What is new in version 15.7.3:

• The "optimize all", help, push, and simplify commands have been improved.
• Additional and better options are available in the symbolic math library.
• The functionality of the library is now very similar to the application.
• All scripts required to make a new release of Mathomatic have now been published in the source code distribution.
• Minor bugs were fixed.
• Automatic searching for a variable name in all equation spaces is now supported; the result, if found, is selected and displayed.
• Use "/" to search forwards and "#" to search backwards from the current equation at the main prompt.
