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
