NAME
       SRC/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 (character uplo, integer m, integer n, complex*16 alpha,
       complex*16 beta, complex*16, dimension( lda, * ) a, integer lda)
       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).
           !>
