HPL_dlaswp02N(3)             HPL Library Functions            HPL_dlaswp02N(3)


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.
