CLASET(3)      LAPACK routine of NEC Numeric Library Collection      CLASET(3)



NAME
       CLASET

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



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




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

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

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

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

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