CLASET(3)                  MathKeisan LAPACK routine                 CLASET(3)



NAME
       CLASET  - a 2-D array A to BETA on the diagonal and ALPHA on the offdi-
       agonals

SYNOPSIS
       SUBROUTINE CLASET( UPLO, M, N, ALPHA, BETA, A, LDA )

           CHARACTER      UPLO

           INTEGER        LDA, M, N

           COMPLEX        ALPHA, BETA

           COMPLEX        A( LDA, * )

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


ARGUMENTS
       UPLO    (input) 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) INTEGER
               On entry, M specifies the number of rows of A.

       N       (input) INTEGER
               On entry, N specifies the number of columns of A.

       ALPHA   (input) COMPLEX
               All the offdiagonal array elements are set to ALPHA.

       BETA    (input) COMPLEX
               All the diagonal array elements are set to BETA.

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