Disable the permutation during the schur complement computation

Hi All,

I am using Pardiso from MKL to compute the Schur complement of a matrix, and I realize that it permutes the matrix during the reordering and numerical factorization.

Is there a way to disable that permutation ? I am doing a partial factorization of a submatrix involved in a more large project, and I just want to compute the Schur complement without any ordering or numerical pivoting.

Thanks
