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 (character uplo, integer m, integer n, complex alpha, complex beta, complex, dimension( lda, * ) a, integer lda)

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).
!>
