dReDistribute_A()

int_t dReDistribute_A	(	SuperMatrix *	A,
		dScalePermstruct_t *	ScalePermstruct,
		Glu_freeable_t *	Glu_freeable,
		int_t *	xsup,

Purpose
=======
  Re-distribute A on the 2D process mesh.

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.

ScalePermstruct (input) dScalePermstruct_t*
       The data structure to store the scaling and permutation vectors
       describing the transformations performed to the original matrix A.

Glu_freeable (input) *Glu_freeable_t
       The global structure describing the graph of L and U.

grid   (input) gridinfo_t*
       The 2D process mesh.

colptr (output) int*

rowind (output) int*

a      (output) double*

Return value
============
  > 0, working storage (in bytes) required to perform redistribution.
       (excluding LU factor size)
