HPL_dlaswp02N HPL 2.2 Library Functions February 24, 2016

Name

HPL_dlaswp02N pack rows of A into columns of W.

Synopsis

#include "hpl.h"

void HPL_dlaswp02N( const int M, const int N, const double * A, const int LDA, double * W0, double * W, const int LDW, const int * LINDXA, const int * LINDXAU );

Description

HPL_dlaswp02N packs scattered rows of an array A into workspace W. The row offsets in A are specified by LINDXA.

Arguments

M       (local input)                 const int
        On entry, M  specifies the number of rows of A that should be
        copied into W. M must be at least zero.
N       (local input)                 const int
        On entry, N  specifies the length of rows of A that should be
        copied into W. N must be at least zero.
A       (local input)                 const double *
        On entry, A points to an array of dimension (LDA,N). The rows
        of this array specified by LINDXA should be copied into W.
LDA     (local input)                 const int
        On entry, LDA specifies the leading dimension of the array A.
        LDA must be at least MAX(1,M).
W0      (local input/output)          double *
        On exit,  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 output)                double *
        On entry, W  is an array of size (LDW,M). On exit, W contains
        the  rows LINDXA[i] for i in [0..M) of A stored  contiguously
        in W(:,i).
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 M that contains the
        local row indexes of A that should be copied into W.
LINDXAU (local input)                 const int *
        On entry, LINDXAU  is an array of dimension M  that  contains
        the local  row indexes of  U that should be copied into A and
        replaced by the rows of W.
