HPL_dlaswp01N(3)	     HPL Library Functions	      HPL_dlaswp01N(3)

NAME
       HPL_dlaswp01N - copies rows of A	into itself and	into U.

SYNOPSIS
       #include	"hpl.h"

       void  HPL_dlaswp01N(  const  int	 M, const int N, double	* A, const int
       LDA, double * U,	const int LDU, const int * LINDXA, const int * LINDXAU
       );

DESCRIPTION
       HPL_dlaswp01N copies  scattered rows  of	 A  into itself	 and  into  an
       array   U.   The	row offsets in	A  of the source rows are specified by
       LINDXA.	The  destination of those rows are specified by	  LINDXAU.   A
       positive	 value	of  LINDXAU indicates that the array destination is U,
       and A otherwise.

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

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

       A       (local input/output)    double *
	       On entry, A points to an	array of dimension (LDA,N).  The  rows
	       of  this	 array specified by LINDXA should be moved within A or
	       copied into U.

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

       U       (local input/output)    double *
	       On  entry,  U points to an array	of dimension (LDU,N). The rows
	       of A specified by LINDXA	are be copied within this array	 U  at
	       the positions indicated by positive values of LINDXAU.

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

       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 moved within	 A  or
	       or copied into U.

       LINDXAU (local input)	       const int *
	       On entry, LINDXAU  is an	array of dimension  M  that   contains
	       the  local   row	indexes	of  U  where the rows of  A  should be
	       copied at. This array also contains the	local row offsets in A
	       where some of the rows of A should be  moved  to.   A  positive
	       value  of   LINDXAU[i]  indicates that the row  LINDXA[i]  of A
	       should be copied	into U at the position	LINDXAU[i];  otherwise
	       the  row	  LINDXA[i]  of	 A  should be moved  at	 the  position
	       -LINDXAU[i] within A.
