    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, * )
    
    
    
         #include <sunperf.h>
    
         void dlacpy(char uplo, int m, int n, double  *da,  int  lda,
                   double *db, int 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).
