   Hi, shicong, according to the np's definition, the matmul for high-dim matrix should be:
   
   ```python3
   x1 = np.random.randn(1, 12, 256, 64).astype(np.float32)
   x2 = np.random.randn(1, 12, 64, 256).astype(np.float32)
   print(np.matmul(x1, x2).shape)
   ```
   
   Output:
   > (1, 12, 256, 256)
   
   Actually, it does the matmul for (256, 64) * (64, 256) for all cells of the first two axes (1, 12).
