NAME
DLACPY  copies all or part of a twodimensional matrix A to another matrix B
SYNOPSIS
 SUBROUTINE DLACPY(

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

CHARACTER
UPLO

INTEGER
LDA, LDB, M, N

DOUBLE
PRECISION A( LDA, * ), B( LDB, * )
PURPOSE
DLACPY copies all or part of a twodimensional 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) DOUBLE PRECISION array, dimension (LDA,N)

The m by n matrix A. If UPLO = aqUaq, only the upper triangle
or trapezoid is accessed; if UPLO = aqLaq, only the lower
triangle or trapezoid is accessed.
 LDA (input) INTEGER

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