Function/Subroutine Documentation

  double precision function ddot (integer N, double precision, dimension(*) DX, integer INCX, double precision, dimension(*) DY, integer INCY)

DDOT

Purpose:

        DDOT forms the dot product of two vectors.
        uses unrolled loops for increments equal to one.

Parameters:
    N

              N is INTEGER
             number of elements in input vector(s)

    DX

              DX is DOUBLE PRECISION array, dimension ( 1 + ( N - 1 )*abs( INCX ) )

    INCX

              INCX is INTEGER
             storage spacing between elements of DX

    DY

              DY is DOUBLE PRECISION array, dimension ( 1 + ( N - 1 )*abs( INCY ) )

    INCY

              INCY is INTEGER
             storage spacing between elements of DY
