HPL_dlaswp03N HPL 2.2 Library Functions February 24, 2016

Name

HPL_dlaswp03N copy rows of W into U.

Synopsis

#include "hpl.h"

void HPL_dlaswp03N( const int M, const int N, double * U, const int LDU, const double * W0, const double * W, const int LDW );

Description

HPL_dlaswp03N copies columns of W into rows of an array U. The destination in U of these columns contained in W is stored within W0.

Arguments

M       (local input)                 const int
        On entry, M  specifies  the  number  of columns of  W  stored
        contiguously that should be copied into U. M must be at least
        zero.
N       (local input)                 const int
        On entry,  N  specifies  the  length of columns of  W  stored
        contiguously that should be copied into U. N must be at least
        zero.
U       (local input/output)          double *
        On entry, U points to an array of dimension (LDU,N).  Columns
        of W are copied as rows within this array U at  the positions
        specified in W0.
LDU     (local input)                 const int
        On entry, LDU specifies the leading dimension of the array U.
        LDU must be at least MAX(1,M).
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,M),  that contains data
        to be copied into U. For i in [0..M),  entries W(:,i)  should
        be copied into the row or 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).
