LAPACK-3: initializes a 2-D array A to BETA on the diagonal and ALPHA on the offdiagonals

```NAME
LAPACK-3  - initializes 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).
