NAME
       dger.f -

SYNOPSIS
   Functions/Subroutines
       subroutine dger (M, N, ALPHA, X, INCX, Y, INCY, A, LDA)
	   DGER

Function/Subroutine Documentation
   subroutine dger (integerM, integerN, double precisionALPHA, double precision, dimension(*)X, integerINCX, double precision, dimension(*)Y,
       integerINCY, double precision, dimension(lda,*)A, integerLDA)
       DGER Purpose:

	    DGER   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.

       Parameters:
	   M

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

	   N

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

	   ALPHA

		     ALPHA is DOUBLE PRECISION.
		      On entry, ALPHA specifies the scalar alpha.

	   X

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

	   INCX

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

	   Y

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

	   INCY

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

	   A

		     A is DOUBLE PRECISION 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

		     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 ).
