NAME
     claset - initialize a 2-D array A to BETA  on  the  diagonal
     and ALPHA on the offdiagonals

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

     CHARACTER UPLO

     INTEGER LDA, M, N

     COMPLEX ALPHA, BETA

     COMPLEX A( LDA, * )



     #include <sunperf.h>

     void claset(char uplo, int m, int n, complex  *calpha,  com-
               plex *cbeta, complex *ca, int 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 triangu-
               lar  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).
