NAME
       DLASET  -  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).
