NAME
       DLACPY - copie all or part of a two-dimensional 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 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) DOUBLE PRECISION array, dimension (LDA,N)
	       The  m  by  n matrix A.	If UPLO = 'U', only the upper triangle or trapezoid is accessed; if UPLO = 'L', 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).
