Hello,
I would need to solve P linear systems if possible without using loops. I was thinking about LU factorization which in my case is quite fast. I know how to approach the problem for a 2d matrix. But what should i do for the case of a 3d matrix M(N,N,:)?
thanks in advance!

Convert it to a sparse block diagonal system. Then use backslash. No problem.
