项目描述

Mathomatic is a portable, general-purpose computer algebra system (CAS) that can solve, differentiate, simplify, combine, and compare algebraic equations, perform standard, complex number, modular, and polynomial arithmetic, etc. It does some calculus and is very easy to compile/install, learn, and use. The symbolic math application with a simple command-line interface is designed to be a colorful algebra calculator that is reliable, responsive, and convenient to use. The symbolic math library is lightweight and easy to include in other software, due to being written entirely in C with no additional dependencies.

15.8.1

一些重要的缺少文件列入了，开始在此版本中，采取不使用 Mathomatic 的臆测。已修复的生成文件和弹性模量的简化。
标签: Documentation, Bugfixes
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.

15.8.0

这是主要 bug 修正版本。它通过表达式在他们虚数，则修复司的简化。这将允许复杂指数表达式 （如 tan(x) 和 cot(x) 的扩产，现在很好地简化与 m4 Mathomatic。这是仅在 Mathomatic (15.7.3） 以前的版本中的 bug。有了几个其他轻微改善。
标签: bugfix, Enhancements
This is mainly a bugfix release. 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.

15.7.3

优化"所有，"帮助、 推动，并简化命令已得到改进。符号数学库提供更多更好的选项。现在非常类似于应用程序库的功能。现已出版使 Mathomatic 的新发行版所需的所有脚本的源代码分发。小 bug 被固定。现在支持自动搜索所有方程空间中的变量名 ；结果，如果发现、 选择并显示。使用"/"来搜索批转和"#"若要从当前方程的主提示符向后搜索。
标签: Maintenance, Enhancements
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.

15.7.1

成千上万分离器的常量被去除了，因为许多标准 C 库中的 bug。改进了测试和错误/警告消息。现在在调试时输出只有有用的消息。添加"unfactor 计数"的命令是为了扩大和条款的任何多项式的计数。有帮助着色被添加到帮助命令。更多的命令不要现在 ； 忽略的"重复"的前缀通常它意味着要做到全简化，除非它是一个重复的函数。衍生金融工具的命令被固定时导数为零时停止。测试现在下这个软件的工作。
标签: Enhancements, Bugfixes, Stable
Thousands separators in constants were removed, due to bugs in many standard C libraries. The tests and error/warning messages were improved. Only helpful messages are output when debugging now. An "unfactor count" command was added to expand and count the number of terms of any polynomial. Helpful coloring was added to the help command. More commands do not ignore the "repeat" prefix now; often it means to do full simplification, unless it serves a repeat function. The derivative command was fixed to stop when the derivative reaches zero. The tests now work under CygWin.

15.7.0

计算命令允许为便于使用，已更正 nintegrate 方程-数量-range 参数 （数值整合) 命令现在允许在命令行上的边界和更正的鸿沟命令现在允许股息和除数在命令行上。Plot 命令允许 ^ 在命令行上为易用性。C 代码清理完成并编译选项被更正。符号数学库中的显示命令已被纠正，要工作，因为它应该。变量可以计数与新的"变量计数"命令。
标签: cleanup, Enhancements
The calculate command allows an equation-number-range argument for ease of use, the corrected nintegrate (numerical integrate) command now allows bounds on the command line, and the corrected divide command now allows the dividend and divisor on the command line. The plot command allows ^ on the command line for ease of use. C code cleanup was done and compilation options were corrected. The display command in the symbolic math library was corrected to work as it should. Variables can be counted with the new "variables count" command.
