ZLASET(3)                  MathKeisan LAPACK routine                 ZLASET(3)



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

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

           CHARACTER      UPLO

           INTEGER        LDA, M, N

           COMPLEX*16     ALPHA, BETA

           COMPLEX*16     A( LDA, * )

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

       BETA    (input) COMPLEX*16
               All the diagonal array elements are set to BETA.

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