this is because the matrix coefficients are modified by SuperLU
itself, so we have to make a copy to preserve the user data.
Actually, it would be nice sometimes to have methods which store the
decomposition over the input data (where applicable). This could come
handy for dense decompositions as well if the original matrix is not
required anymore (saving memory and a copy operation).
