* \brief Converts this cuMat matrix to the corresponding Eigen matrix. * Note that Eigen does not support batched matrices. Hence, this * conversion is only possible, if * a) the matrix has a compile-time batch size of 1, or * b) the matrix has a dynamic batch size and the batch size is 1 during runtime. * * * Design decision: * Converting between cuMat and Eigen

	 * \return the Eigen matrix with the contents of this matrix.
