dlacpy(3F)

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).
