NAME

CLACPY - copie all or part of a two-dimensional matrix A to another matrix B

SYNOPSIS

SUBROUTINE CLACPY(
UPLO, M, N, A, LDA, B, LDB )

CHARACTER UPLO

INTEGER LDA, LDB, M, N

COMPLEX A( LDA, ∗ ), B( LDB, ∗ )

PURPOSE

CLACPY 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. = ’U’:      Upper triangular part
= ’L’:      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 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.

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

B       (output) COMPLEX 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).
