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 posi-
	     tions 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.
