dGetHWPM()

void dGetHWPM	(	SuperMatrix *	A,
		gridinfo_t *	grid,
		dScalePermstruct_t *	ScalePermstruct
	)

Purpose
=======
  Get perm_r from HWPM, heavy-weight perfect matching, as a
  numerical pivoting permutation.

Arguments
=========

A      (input) SuperMatrix*
       The distributed input matrix A of dimension (A->nrow, A->ncol).
       A may be overwritten by diag(R)*A*diag(C)*Pc^T.
       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.

grid   (input) gridinfo_t*
       SuperLU's 2D process mesh.

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