* @brief This comments show how operators is defined in InfiniTensor. The
* constructor can create output tensors for the operator or not, which
* depends on `graph`.
*
* @param graph If graph is not empty, create outputs in the constructor.
* Otherwise, check the provided shape with the results of `inferShape` in
* `checkValid`.
* @param C C is the output of Matmul. If outputs are going to be created in
* the constructor, C should be an empty Ref.
