    Purpose   
    =======   

    DLASET initializes an m-by-n matrix A to BETA on the diagonal and   
    ALPHA on the offdiagonals.   

    Arguments   
    =========   

    UPLO    (input) CHARACTER*1   
            Specifies the part of the matrix A to be set.   
            = 'U':      Upper triangular part is set; the strictly lower   
                        triangular part of A is not changed.   
            = 'L':      Lower triangular part is set; the strictly upper   
                        triangular part of A is not changed.   
            Otherwise:  All of the matrix A is set.   

    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.   

    ALPHA   (input) DOUBLE PRECISION   
            The constant to which the offdiagonal elements are to be set.   

    BETA    (input) DOUBLE PRECISION   
            The constant to which the diagonal elements are to be set.   

    A       (input/output) DOUBLE PRECISION array, dimension (LDA,N)   
            On exit, the leading m-by-n submatrix of A is set as follows:   

            if UPLO = 'U', A(i,j) = ALPHA, 1<=i<=j-1, 1<=j<=n,   
            if UPLO = 'L', A(i,j) = ALPHA, j+1<=i<=m, 1<=j<=n,   
            otherwise,     A(i,j) = ALPHA, 1<=i<=m, 1<=j<=n, i.ne.j,   

            and, for all UPLO, A(i,i) = BETA, 1<=i<=min(m,n).   

    LDA     (input) INTEGER   
            The leading dimension of the array A.  LDA >= max(1,M).
