DAXPY constant times a vector plus a vector.


    uses unrolled loops for increments equal to one.

N

          N is INTEGER


         number of elements in input vector(s)

DA

          DA is DOUBLE PRECISION


           On entry, DA specifies the scalar alpha.

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
