        alpha: Option<T>,

Performs General Matrix multiplication: https://en.wikipedia.org/wiki/Basic_Linear_Algebra_Subprograms#Level_3

• A' = transpose(A) if transA else A

• B' = transpose(B) if transB else B

Compute Y = alpha * A' * B' + beta * C, where input tensor A has shape (M, K) or (K, M), input tensor B has shape (K, N) or (N, K), input tensor C is broadcastable to shape (M, N), and output tensor Y has shape (M, N). A will be transposed before doing the computation if attribute transA is true, same for B and transB.

Args

• A(Tensor<T>) - Input tensor A. The shape of A should be (M, K) if transA is false, or (K, M) if transA is true.

• B(Tensor<T>) - Input tensor B. The shape of B should be (K, N) if transB is false, or (N, K) if transB is true.

• C(Option<Tensor<T>>) - Optional input tensor C. The shape of C should be unidirectional broadcastable to (M, N).

• alpha(Option<T>) - Optional scalar multiplier for the product of input tensors A * B.

• beta(Option<T>) - Optional scalar multiplier for input tensor C.

• transA(bool) - Whether A should be transposed.

• transB(bool) - Whether B should be transposed.

Returns

A Tensor<T> of shape (M, N).

      let input_1 = input_1::input_1(); // shape [5;4]
      let input_2 = input_2::input_2(); // shape [1;5]

      let y = NNTrait::gemm(
