NAME

       LAPACK-3  -  initializes  an  m-by-n  matrix  A  to  BETA on the diagonal and ALPHA on the
       offdiagonals

SYNOPSIS

       SUBROUTINE DLASET( UPLO, M, N, ALPHA, BETA, A, LDA )

           CHARACTER      UPLO

           INTEGER        LDA, M, N

           DOUBLE         PRECISION ALPHA, BETA

           DOUBLE         PRECISION A( LDA, * )

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).
