One way is to copy and paste it :-)

That said, it is worth knowing that a⊗b is the same as a.dot(b), so you can use whichever you prefer.

We will consider renaming `a.dot(b)` to `matmul(a, b)` to accurately reflect the operator’s mathematical properties and make it familiar to TensorFlow users. 

Previously `dot` was chosen over `matmul` because of naming convention concerns (acronyms aren’t common in Swift) and that we wanted to make it short (so full names like `a.matrixMultiplied(by: b)` isn’t acceptable).  That said, `matmul` is really a word of art and thus should be preferred.  

We should consider redefining ⊗ operator as well, since ⊗ often denotes outer product and Kronecker product.
