    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).
