[SYSTEMML-2434] Support for matrix market symmetry general/symmetric This patch introduces support for matrix market symmetry types beyond general in CP and Spark execution modes. Specifically, we now also support symmetric inputs that are expanded into general matrices during read. We do not support skew-symmetric (although easy to add) because R does not implement this yet and hence we cannot compare for testing.
