subroutine claset (UPLO, M, N, ALPHA, BETA, A, LDA)
CLASET initializes the off-diagonal elements and the diagonal
elements of a matrix to given values.
subroutine claset (characterUPLO, integerM, integerN, complexALPHA,
complexBETA, complex, dimension( lda, * )A, integerLDA)
CLASET initializes the off-diagonal elements and the diagonal elements
of a matrix to given values.
CLASET initializes a 2-D array A to BETA on the diagonal and
ALPHA on the offdiagonals.
UPLO is CHARACTER*1
Specifies the part of the matrix A to be set.
= 'U': Upper triangular part is set. The lower triangle
= 'L': Lower triangular part is set. The upper triangle
Otherwise: All of the matrix A is set.
M is INTEGER
On entry, M specifies the number of rows of A.
N is INTEGER
On entry, N specifies the number of columns of A.
ALPHA is COMPLEX
All the offdiagonal array elements are set to ALPHA.
BETA is COMPLEX
All the diagonal array elements are set to BETA.
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 is INTEGER
The leading dimension of the array A. LDA >= max(1,M).
