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

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

	   CHARACTER	  UPLO

	   INTEGER	  LDA, M, N

	   COMPLEX	  ALPHA, BETA

	   COMPLEX	  A( LDA, * )

PURPOSE
       CLASET 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
	       All the offdiagonal array elements are set to ALPHA.

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

       A       (input/output) COMPLEX 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).
