* @note GEMM: The tensors a, b, c, d must have the same data type. You should not mix data types when calling this function.

* @param[in] a First input tensor info (Matrix A or Vector A). Data type supported: BFLOAT16/F16/F32
* @param[in] b Second input tensor info (Matrix B). Data type supported: same as @p a
