We all know the problem that computation time explodes when simulating systems with big matrices. I got just this problem, but I have the advantage that I know that my matrices are symmetric.My question is thus: Do you know a way to decrease computation time if I know that my matrices are symmetry?What I want in particular are the follwing two things:A representation for my symmetric matrices which uses only the relevant entriesAn algorithm that lets me efficiently multiply two matrices in this representation
How to decrease computation time for symmetric matrices?
