symvarsub collects routines useful for performing variable subsitutions in collections of SymPy expressions.
It provides an alternative to sympy.utilities.lambdify, its main benefit is much faster compile times thanks to caching of object file.
E.g. do:
pip install --user --upgrade -r http://raw.github.com/bjodah/symvarsub/master/requirements.txt
pip install --user --upgrade http://github.com/bjodah/symvarsub/archive/v0.0.9.tar.gz
(modify to your needs)
- fastinverse generating C code for fast calculation of inverses (table lookup -> polynomial interpolation -> newton refinement)
