I need help from someone more fluent in APL than I am lol

I've been looking up where the mathproglangy convention of treating the dot product as the same as matrix multiplication came from and it seems like APL was a big influence.

http://stackoverflow.com/questions/20424228/how-come-x-in-apl-works-for-both-matrices-and-vectors/20704876#20704876

So there's this answer and I wanted to know what part of the code corresponds to these 2 steps: "cut A into slices along its last axis, do the same with B along its first axis"

Also if anyone could tell me how these particular operations are done in one of the more modern variants like K or Q.
