Wouldn't it be more efficient to only create a vector of col and row indices that is reduced of one element for each determinant development ? So in the end your 'submatrix' is like a view on the original matrix, instead of copying the same values multiple times ?

I did not try to reach high performances because I don't have the need. Currently, I use it only in init().
