> 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.
