* const customMatmul = (node) =>

|
* node.inputs[0], node.inputs[1],
|
* node.attrs['transpose_a'], node.attrs['transpose_b']);

|
* tf.registerOp('MatMul', customMatmul);
|
* ```
|
* The inputs and attrs of the node object are based on the TensorFlow op
|
* registry.
|
*
|
* @param name The Tensorflow Op name.
|
* @param opFunc An op function which is called with the current graph node
|
* during execution and needs to return a tensor or a list of tensors. The node
|
* has the following attributes:
|
* - attr: A map from attribute name to its value
|
* - inputs: A list of input tensors
