NAME
       ZLASET - initialize a 2-D array A to BETA on the diagonal and ALPHA on the offdiagonals

SYNOPSIS
       SUBROUTINE ZLASET( UPLO, M, N, ALPHA, BETA, A, LDA )

	   CHARACTER	  UPLO

	   INTEGER	  LDA, M, N

	   COMPLEX*16	  ALPHA, BETA

	   COMPLEX*16	  A( LDA, * )

PURPOSE
       ZLASET initializes a 2-D array 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 lower triangle is unchanged.  = 'L':
	       Lower triangular part is set. The upper triangle is unchanged.  Otherwise:  All of the matrix A is set.

       M       (input) INTEGER
	       On entry, M specifies the number of rows of A.

       N       (input) INTEGER
	       On entry, N specifies the number of columns of A.

       ALPHA   (input) COMPLEX*16
	       All the offdiagonal array elements are set to ALPHA.

       BETA    (input) COMPLEX*16
	       All the diagonal array elements are set to BETA.

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