> Currently several of the Stream Evaluators that work with matrices are 
> creating multiple copies of the underlying multi-dimensional arrays. This can 
> lead to excessive memory usage. This ticket will change these implementations 
> so copies of the multi-dimensional arrays that back a matrix are only copied 
> when the *copyOf* function is used.
