```       LAPACK-3 - initializes 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).
