.TH ZLACPY l "15 June 2000" "LAPACK version 3.0" ")"
.SH NAME
ZLACPY - copie all or part of a two-dimensional matrix A to another matrix B
.SH SYNOPSIS
.TP 19
SUBROUTINE ZLACPY(
UPLO, M, N, A, LDA, B, LDB )
.TP 19
.ti +4
CHARACTER
UPLO
.TP 19
.ti +4
INTEGER
LDA, LDB, M, N
.TP 19
.ti +4
COMPLEX*16
A( LDA, * ), B( LDB, * )
.SH PURPOSE
ZLACPY copies all or part of a two-dimensional matrix A to another matrix B.
.SH ARGUMENTS
.TP 8
UPLO (input) CHARACTER*1
Specifies the part of the matrix A to be copied to B.
= 'U': Upper triangular part
.br
= 'L': Lower triangular part
.br
Otherwise: All of the matrix A
.TP 8
M (input) INTEGER
The number of rows of the matrix A. M >= 0.
.TP 8
N (input) INTEGER
The number of columns of the matrix A. N >= 0.
.TP 8
A (input) COMPLEX*16 array, dimension (LDA,N)
The m by n matrix A. If UPLO = 'U', only the upper trapezium
is accessed; if UPLO = 'L', only the lower trapezium is
accessed.
.TP 8
LDA (input) INTEGER
The leading dimension of the array A. LDA >= max(1,M).
.TP 8
B (output) COMPLEX*16 array, dimension (LDB,N)
On exit, B = A in the locations specified by UPLO.
.TP 8
LDB (input) INTEGER
The leading dimension of the array B. LDB >= max(1,M).
