CSympy and C++

[Matheus Queiroz]

Hi!

I'm a undergraduate student in need of a symbolic library.

I know enough C++ and Qt Framework to get into some "adventures".

I heard about sympy and I simply loved it. It's simple, efficient and has everything that I currently need.

My question:

Can I use it in C++?

If yes... is there any documentation on how to use it in C++ code?

Sorry, folks. But I really have no time to learn Python up to the level I am currently programming in C++ (Not to mention that my scientific work uses a lot of matrices that are dynamically allocated).

Thanks, I am glad you like it.

You can call Python from C++ (using Cython or by hand using Python
C/API) if that is what you want.

I found documentation how to call Python from C or C++ here:

https://docs.python.org/2/extending/embedding.html

I would mention that Python is very easy to learn, compared to C++,
and I would definitely recommend it to you. You can use NumPy for
dynamically allocated matrices and arrays.

That being said, we also have a pure C++ library:
https://github.com/sympy/csympy, and you can use it directly from C++
without any Python dependency. But it currently only has a subset of
all the SymPy functionality. To get a full featured computer algebra
system, use SymPy from Python. Use CSymPy if SymPy in Python is too
slow for your application.

Thanks a lot, Ondřej.

That will do the work just fine.
