> It seems like we have to define all the write cmd in all the possible systemML if else
branch. 
> It could become very complicated for the nested function call to take this into account.
> I think systemML should automatically insert write(file, empty_matrix) if the all the
branches of the DAG doesn't contains the write statement
> Note that in reference to the mlCtx, this pb manifest itself into big stack trace
> Note that this bug is also related to https://issues.apache.org/jira/browse/SYSTEMML-1422
