**NAME**

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).
