Python wrappers to the C++ library SymEngine, a fast C++ symbolic manipulation library.
Install prerequisites.
CMake >= 2.8.7
Python2 >= 2.6 or Python3 >= 3.3
Cython >= 0.19.1
SymEngine >= 0.1.0
For SymEngine, only a specific commit (see symengine_version.txt) is supported. Latest git master branch may not work as there may be breaking changes in SymEngine.
Python wrappers can be installed by,
python setup.py install
Additional options to setup.py are
python setup.py install build
--symengine-dir=/path/to/symengine/install/dir # Path to SymEngine install directory or build directory
--compiler=mingw32|msvc|cygwin # Select the compiler for Windows
--generator=cmake-generator # CMake Generator
--build-type=Release|Debug # Set build-type for multi-configuration generators like MSVC
--define="var1=value1;var2=value2" # Give options to CMake
Standard options to setup.py like --user, --prefix can be used to configure install location
Use SymEngine from Python as follows:
>>> from symengine import var
>>> var("x y z")
(x, y, z)
>>> e = (x+y+z)**2
>>> e.expand()
2*x*y + 2*x*z + 2*y*z + x**2 + y**2 + z**2
You can read Python tests in symengine/tests to see what features are
implemented.
