I asked on MSE (with better detail) but haven't heard a response yet: linear algebra - Optimized Distance Calculation for Data Cube - Mathematics Stack Exchange Any help would be great!

What is meant by a "matrix slice" and how are you defining the "distance" between two "matrix slices"?

I assume that "" and "" are the "matrix slices" but I don't know what those are.
