NAME
zlaset.f -

SYNOPSIS
Functions/Subroutines
subroutine zlaset (UPLO, M, N, ALPHA, BETA, A, LDA)
ZLASET initializes the off-diagonal elements and the diagonal elements of a matrix to given values.

Function/Subroutine Documentation
subroutine zlaset (characterUPLO, integerM, integerN, complex*16ALPHA, complex*16BETA, complex*16, dimension( lda, * )A, integerLDA)
ZLASET initializes the off-diagonal elements and the diagonal elements of a matrix to given values.

Purpose:

ZLASET 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*16
All the offdiagonal array elements are set to ALPHA.

BETA

BETA is COMPLEX*16
All the diagonal array elements are set to BETA.

A

A is COMPLEX*16 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).
