C / C ++ / Obj-C中的符号数学库 [英] Symbolic Math Library in C/C++/Obj-C

问题描述

我想在iPhone上实现一个图形计算器。我正在寻找一个库，可以接受表达式或函数的字符串，让我操纵他们（找到导数，截距，零等）。有没有这样的存在？

I am trying to implement a graphing calculator on the iPhone. I am looking for a library that can take strings of expressions or functions and let me manipulate them (find derivatives, intercepts, zeros, etc). Does anything like this exist?

推荐答案

有 GiNaC for C ++。 GPL许可和积极维护，上次更新只有一个月前。我发现旧的链接，许多其他似乎不再存在;也许人们发现使用GiNaC更容易吗？

There's GiNaC for C++. GPL-licensed and actively maintained, last update only a month ago. I found old links to many others that don't seem to exist anymore; perhaps people simply found it easier to use GiNaC?
