SYNOPSIS

Functions/Subroutines


subroutine DLACPY (uplo, m, n, a, lda, b, ldb)
DLACPY copies all or part of one two-dimensional array to another.

Function/Subroutine Documentation

subroutine DLACPY (character uplo, integer m, integer n, double precision, dimension( lda, * ) a, integer lda, double precision, dimension( ldb, * ) b, integer ldb)

DLACPY copies all or part of one two-dimensional array to another.

Purpose:

!>
!> DLACPY copies all or part of a two-dimensional matrix A to another
!> matrix B.
!>

Parameters

UPLO 

!>          UPLO is CHARACTER*1
!>          Specifies the part of the matrix A to be copied to B.
!>          = 'U':      Upper triangular part
!>          = 'L':      Lower triangular part
!>          Otherwise:  All of the matrix A
!>

M

!>          M is INTEGER
!>          The number of rows of the matrix A.  M >= 0.
!>

N

!>          N is INTEGER
!>          The number of columns of the matrix A.  N >= 0.
!>

A

!>          A is DOUBLE PRECISION array, dimension (LDA,N)
!>          The m by n matrix A.  If UPLO = 'U', only the upper triangle
!>          or trapezoid is accessed; if UPLO = 'L', only the lower
!>          triangle or trapezoid is accessed.
!>

LDA

!>          LDA is INTEGER
!>          The leading dimension of the array A.  LDA >= max(1,M).
!>

B

!>          B is DOUBLE PRECISION array, dimension (LDB,N)
!>          On exit, B = A in the locations specified by UPLO.
!>

LDB

!>          LDB is INTEGER
!>          The leading dimension of the array B.  LDB >= max(1,M).
!>
