CLASET(l) ) CLASET(l)
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).
