HPL_dlaswp04N(3)	     HPL Library Functions	      HPL_dlaswp04N(3)

NAME
       HPL_dlaswp04N - copy rows of U in A and replace them with columns of W.

SYNOPSIS
       #include	"hpl.h"

       void  HPL_dlaswp04N(  const int M0, const int M1, const int N, double *
       U, const	int LDU, double	* A, const int LDA, const double *  W0,	 const
       double *	W, const int LDW, const	int * LINDXA, const int	* LINDXAU );

DESCRIPTION
       HPL_dlaswp04N  copies  M0 rows of U into	A and replaces those rows of U
       with columns of W. In addition M1 - M0 columns of  W  are  copied  into
       rows of U.

ARGUMENTS
       M0      (local input)	       const int
	       On  entry,  M0 specifies	the number of rows of U	that should be
	       copied into  A  and replaced by columns of  W.  M0 must	be  at
	       least zero.

       M1      (local input)	       const int
	       On  entry,  M1 specifies	the number of columns of W that	should
	       be copied into rows of U. M1 must be at least zero.

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

       U       (local input/output)    double *
	       On  entry,   U  points to  an array of dimension	(LDU,N).  This
	       array contains the rows that are	to be copied into A.

       LDU     (local input)	       const int
	       On entry, LDU specifies the leading dimension of	the  array  U.
	       LDU must	be at least MAX(1,M1).

       A       (local output)	       double *
	       On  entry,  A points to an array	of dimension (LDA,N). On exit,
	       the  rows of this array specified by  LINDXA  are  replaced  by
	       rows of U indicated by LINDXAU.

       LDA     (local input)	       const int
	       On  entry,  LDA specifies the leading dimension of the array A.
	       LDA must	be at least MAX(1,M0).

       W0      (local input)	       const double *
	       On entry,  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 input)	       const double *
	       On entry, W  is an array	of size	(LDW,M0+M1),   that   contains
	       data  to	 be copied into	U.  For	i in [M0..M0+M1),  the entries
	       W(:,i) are copied into the row W0(i*LDW)	of U.

       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  M0	containing the
	       local row indexes A into	which rows of U	are copied.

       LINDXAU (local input)	       const int *
	       On entry, LINDXAU  is an	array of dimension M0  that   contains
	       the  local   row	indexes	of  U that should be copied into A and
	       replaced	by the columns of W.
