NAME
       zlaset.f -

SYNOPSIS
   Functions/Subroutines
       subroutine zlaset (UPLO, M, N, ALPHA, BETA, A, LDA)
           ZLASET initializes the off-diagonal elements and the diagonal
           elements of a matrix to given values.

Function/Subroutine Documentation
   subroutine zlaset (characterUPLO, integerM, integerN, complex*16ALPHA,
       complex*16BETA, complex*16, dimension( lda, * )A, integerLDA)
       ZLASET initializes the off-diagonal elements and the diagonal elements
       of a matrix to given values.

       Purpose:

            ZLASET initializes a 2-D array A to BETA on the diagonal and
            ALPHA on the offdiagonals.

       Parameters:
           UPLO

                     UPLO is CHARACTER*1
                     Specifies the part of the matrix A to be set.
                     = 'U':      Upper triangular part is set. The lower triangle
                                 is unchanged.
                     = 'L':      Lower triangular part is set. The upper triangle
                                 is unchanged.
                     Otherwise:  All of the matrix A is set.

           M

                     M is INTEGER
                     On entry, M specifies the number of rows of A.

           N

                     N is INTEGER
                     On entry, N specifies the number of columns of A.

           ALPHA

                     ALPHA is COMPLEX*16
                     All the offdiagonal array elements are set to ALPHA.

           BETA

                     BETA is COMPLEX*16
                     All the diagonal array elements are set to BETA.

           A

                     A is COMPLEX*16 array, dimension (LDA,N)
                     On entry, the m by n matrix A.
                     On exit, A(i,j) = ALPHA, 1 <= i <= m, 1 <= j <= n, i.ne.j;
                              A(i,i) = BETA , 1 <= i <= min(m,n)

           LDA

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