       subroutine cgeru (M, N, ALPHA, X, INCX, Y, INCY, A, LDA)

Function/Subroutine Documentation
   subroutine cgeru (integerM, integerN, complexALPHA, complex, dimension(*)X,
       integerINCX, complex, dimension(*)Y, integerINCY, complex,
       dimension(lda,*)A, integerLDA)
       CGERU Purpose:

	    CGERU  performs the rank 1 operation

	       A := alpha*x*y**T + A,

	    where alpha is a scalar, x is an m element vector, y is an n element
	    vector and A is an m by n matrix.


		     M is INTEGER
		      On entry, M specifies the number of rows of the matrix A.
		      M must be at least zero.


		     N is INTEGER
		      On entry, N specifies the number of columns of the matrix A.
		      N must be at least zero.


		      On entry, ALPHA specifies the scalar alpha.


		     X is COMPLEX array of dimension at least
		      ( 1 + ( m - 1 )*abs( INCX ) ).
		      Before entry, the incremented array X must contain the m
		      element vector x.


		     INCX is INTEGER
		      On entry, INCX specifies the increment for the elements of
		      X. INCX must not be zero.


		     Y is COMPLEX array of dimension at least
		      ( 1 + ( n - 1 )*abs( INCY ) ).
		      Before entry, the incremented array Y must contain the n
		      element vector y.


		     INCY is INTEGER
		      On entry, INCY specifies the increment for the elements of
		      Y. INCY must not be zero.


		     A is COMPLEX array of DIMENSION ( LDA, n ).
		      Before entry, the leading m by n part of the array A must
		      contain the matrix of coefficients. On exit, A is
		      overwritten by the updated matrix.


		     LDA is INTEGER
		      On entry, LDA specifies the first dimension of A as declared
		      in the calling (sub) program. LDA must be at least
		      max( 1, m ).
