double precision function DDOT (n, dx, incx, dy, incy)
DDOT

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
