Matlab doesn't broadcast (https://www.mathworks.com/help/matlab/ref/dot.html), but I think your interpretation makes a lot of sense.

It would be nicer to use a for loop in dot.cc, rather than repmat which would require more memory usage (if only temporarily).

I'm thinking it would be nice if automatic broadcasting also worked in the dot function, so it would compute dot product between one and many vectors. Like so:
