How can I perform symbolic computation in a C++ program?

[Andrew732]

Don't know where else in Phyiscs Forums or on the internet in general to ask this, and if it's inappropriate here, I apologize. My question is: is there an open source library or resource that I can access from a C++ program to perform symbolic computation on the level of something like Maple or Mathematica? Accessing the Maple or Mathematica engines from my program is unfortunately out of the question. There are numerous small C++ libraries (SymbolicC++, Mathomatic, Ginac, etc.) but they are almost trivial compared to Maple, for example. Thanks for any advice or ideas.

I don't know how good this is but it popped up at the top of google search using c++ symbolic math parser

And this one

And you might be to tap into these systems either by using the system command to invoke them or to use them as a kind of plugin to your code

There is an open-source Python code called Sage that does symbolic computation. You could download this and study the code. It will be a major undertaking. The code is at:

Alternatively, you might be able to invoke the SAGE python codefrom your program via a system() call (ie you construct a command to run) with your equation to parse, have it save its output to a file and then read it back in. Still it could be a lot of work but I guess it depends on what you're trying to do.

You can try this.

Mathematica has a built in C/C++ library function. Unfortunately, it is going to be hard to find something as powerful as that for open source CAS.
