CLASET(3) LAPACK routine of NEC Numeric Library Collection CLASET(3)
NAME
CLASET
SYNOPSIS
SUBROUTINE CLASET (UPLO, M, N, ALPHA, BETA, A, LDA)
PURPOSE
CLASET initializes a 2-D array A to BETA on the diagonal and
ALPHA on the offdiagonals.
ARGUMENTS
UPLO (input)
UPLO is 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)
M is INTEGER
On entry, M specifies the number of rows of A.
N (input)
N is INTEGER
On entry, N specifies the number of columns of A.
ALPHA (input)
ALPHA is COMPLEX
All the offdiagonal array elements are set to ALPHA.
BETA (input)
BETA is COMPLEX
All the diagonal array elements are set to BETA.
A (input/output)
A is 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)
LDA is INTEGER
The leading dimension of the array A. LDA >= max(1,M).
