Arguments
=========

A      (input) SuperMatrix*
       The distributed input matrix A of dimension (A->nrow, A->ncol).
       The type of A can be: Stype = SLU_NR_loc; Dtype = SLU_D; Mtype = SLU_GE.

perm   (input) int_t*
       Permutation vector describing the transformation performed to
       the original matrix A.

ScalePermstruct (output) zScalePermstruct_t*
       ScalePermstruct->perm_r stores the permutation obtained from HWPM.


Return value
============
ScalePermstruct       = ScalePermstruct->perm_r stores the permutation
