Atomic Vector Multiplication Example
####################################

f(u, v, w)
**********
For this example,
:math:`f : \B{R}^{3m} \rightarrow \B{R}^m`
is defined by :math:`f(u, v, w) = u * v * w`.
where *u* , *v* , and *w* are in :math:`\B{R}^m`.

g(u, v, w)
**********
For this example :math:`g : \B{R}^{3m} \rightarrow \B{R}^m`
is defined by :math:`g_i (u, v, w) = \partial_{u[i]}  f_i (u, v, w)`
