Name

HPL_dlaswp01T copies rows of A into itself and into U.

Synopsis

#include "hpl.h"

void HPL_dlaswp01T( const int M, const int N, double * A, const int LDA, double * U, const int LDU, const int * LINDXA, const int * LINDXAU );

Description

HPL_dlaswp01T 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. Rows of A are stored as columns in U.

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,M). The rows
        of A specified by  LINDXA  are copied within this array  U at
        the  positions indicated by positive values of LINDXAU.  The
        rows of A are stored as columns in U.

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

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.
