Hi, I have a matrix stored as a double* in columnsmajor format. I would like to compute the LU factorisation of a part of the matrix (that is, not the whole matrix, just a sub square of it) inplace, ie I do not want to copy data to an temporary buffer. Is it possible using Eigen ? I saw that PartialPivLU class copy input matrix when constructed... Thx, Vincent
