zlacpy: copies all or part of a two-dimensional matrix A to another matrix B

NAME

ZLACPY - copies all or part of a two-dimensional matrix A to another matrix B

SYNOPSIS

SUBROUTINE ZLACPY(

UPLO, M, N, A, LDA, B, LDB )

    

CHARACTER UPLO

    

INTEGER LDA, LDB, M, N

    

COMPLEX*16 A( LDA, * ), B( LDB, * )

PURPOSE

ZLACPY copies all or part of a two-dimensional matrix A to another matrix B.

ARGUMENTS

UPLO (input) CHARACTER*1

Specifies the part of the matrix A to be copied to B. = aqUaq: Upper triangular part
= aqLaq: Lower triangular part
Otherwise: All of the matrix A

M (input) INTEGER

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

N (input) INTEGER

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

A (input) COMPLEX*16 array, dimension (LDA,N)

The m by n matrix A. If UPLO = aqUaq, only the upper trapezium is accessed; if UPLO = aqLaq, only the lower trapezium is accessed.

LDA (input) INTEGER

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

B (output) COMPLEX*16 array, dimension (LDB,N)

On exit, B = A in the locations specified by UPLO.

LDB (input) INTEGER

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