NAME
claset.f -

SYNOPSIS
Functions/Subroutines
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.

Function/Subroutine Documentation
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.

Purpose:

CLASET initializes a 2-D array A to BETA on the diagonal and
ALPHA on the offdiagonals.

Parameters:
UPLO

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

M is INTEGER
On entry, M specifies the number of rows of A.

N

N is INTEGER
On entry, N specifies the number of columns of A.

ALPHA

ALPHA is COMPLEX
All the offdiagonal array elements are set to ALPHA.

BETA

BETA is COMPLEX
All the diagonal array elements are set to BETA.

A

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

LDA is INTEGER
The leading dimension of the array A.  LDA >= max(1,M).
