HPL_dlaswp04T(3)	      HPL Library Functions		HPL_dlaswp04T(3)

NAME
     HPL_dlaswp04T  -  copy  columns  of  U  in  rows of A and replace them with
     columns of W.

SYNOPSIS
     #include "hpl.h"

     void HPL_dlaswp04T( 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_dlaswp04T  copies  M0	columns  of  U into rows of A and replaces those
     columns of U with columns of W. In addition M1  -	M0  columns  of  W   are
     copied into U.

ARGUMENTS
     M0      (local input)	     const int
	     On  entry,  M0  specifies the number of columns 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 columnns of W that will be
	     copied into U. M1 must be at least zero.

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

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

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

     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 columns 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 column 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 columns of U are copied.

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