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

Function/Subroutine Documentation

subroutine dlacpy (characterUPLO, integerM, integerN, double precision, dimension( lda, * )A, integerLDA, double precision, dimension( ldb, * )B, integerLDB)

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).
