Solving system of linear inequalities in 3 or more variables - Python
make a matrix object and use Crammer's method
I want to solve systems of linear inequalities in 3 or more variables. That is, to find all possible solutions.
I originally found GLPK and tried the python binding, but the last few updates to GLPK changed the APIs and broke the bindings. I haven't been able to find a way to making work. 
I would like to have the symbolic answer, but numeric approximations will be fine too. 
I would also be happy to use a library that solves maximization problem. I can always re-write the problems to be solve in that way.
