HPL_dlaswp02N(3)	      HPL Library Functions		HPL_dlaswp02N(3)

NAME
     HPL_dlaswp02N - pack rows of A into columns of W.

SYNOPSIS
     #include "hpl.h"

     void  HPL_dlaswp02N(  const int M, const int N, const double * A, const int
     LDA, double * W0, double * W, const int LDW, const int * LINDXA, const  int
     * LINDXAU );

DESCRIPTION
     HPL_dlaswp02N  packs scattered rows of an array  A  into workspace  W.  The
     row offsets in A are specified by LINDXA.

ARGUMENTS
     M	     (local input)	     const int
	     On entry, M  specifies the number of  rows  of  A	that  should  be
	     copied into W. M must be at least zero.

     N	     (local input)	     const int
	     On  entry,  N   specifies	the  length  of rows of A that should be
	     copied into W. N must be at least zero.

     A	     (local input)	     const double *
	     On entry, A points to an array of dimension (LDA,N).  The	rows  of
	     this array specified by LINDXA should be copied into W.

     LDA     (local input)	     const int
	     On  entry, LDA specifies the leading dimension of the array A.  LDA
	     must be at least MAX(1,M).

     W0      (local input/output)    double *
	     On exit,  W0  is  an array of size (M-1)*LDW+1, that  contains  the
	     destination offset  in U where the columns of W should be copied.

     W	     (local output)	     double *
	     On  entry,  W  is an array of size (LDW,M). On exit, W contains the
	     rows LINDXA[i] for i in [0..M) of A stored  contiguously in W(:,i).

     LDW     (local input)	     const int
	     On entry, LDW specifies the leading dimension of the array W.   LDW
	     must be at least MAX(1,N+1).

     LINDXA  (local input)	     const int *
	     On entry, LINDXA is an array of dimension M that contains the local
	     row indexes of A that should be copied into W.

     LINDXAU (local input)	     const int *
	     On  entry,  LINDXAU  is an array of dimension M  that  contains the
	     local  row indexes of  U that should be copied into A and	replaced
	     by the rows of W.
