[sympy] Solving matrices in a finite field

2015-07-02 Thread Andrew Mizener
For my project, I need to solve for a matrix X given matrices Y and K. (X*Y=K) The elements of each matrix must be integers modulo a random 256-bit prime. My first attempt at solving this problem used SymPy's mod_inv(n) function. The problem with this is that I'm running out of memory with matr

[sympy] Strange behavior from custom matrix printer

I have implemented a custom matrix printer with "_print_MatrixBase(self, expr)." I am running "jupyter notebook" with the output of "_print_MatrixBase(self, expr)" being given by - def _print_MatrixBase(self, expr): rows = expr.rows cols = expr.cols out_str = ' \\l
