> Fix For: SystemML 1.0

>
> There are instances of binary operations where the input sizes (e.g.,
> matrix-vector) do not cover a potential dense-sparse change, which causes
> outputs to remain in wrong sparse/dense representations. For execution types
> such as singlenode as used in JMLC scenarios this is unnecessary.
> Furthermore, for special cases such as ctable rexpand, the output
> representation cannot be determined upfront and hence, we should similar to
> binary operations, check for sparse/dense conversions accordingly.
