Purpose ======= Get heavy-weight perfect matching (HWPM). Reference: 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. grid (input) gridinfo_t* SuperLU's 2D process mesh. ScalePermstruct (output) dScalePermstruct_t* ScalePermstruct->perm_r stores the permutation obtained from HWPM.
