Functions/Subroutines


subroutine clacpy (UPLO, M, N, A, LDA, B, LDB)
CLACPY copies all or part of one two-dimensional array to another.

Function/Subroutine Documentation

subroutine clacpy (characterUPLO, integerM, integerN, complex, dimension( lda, * )A, integerLDA, complex, dimension( ldb, * )B, integerLDB)

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

Purpose:


CLACPY 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 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


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

B


B is COMPLEX 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).
