RE: QR and permutation matrix
I actually do not need the permutation matrix. I was asking because I wanted to use the QR factorization for solving a system and if the permutation matrix is non-identity then it would have required a few extra lines of code.
Is this the same case for LU factorizations (I.e safe to ignore the permutation matrix)? Graph 3D | QPI | SolveSys |
