if m = 5, then
Uns = ones(1,m) means 1x5 matrix(vector) of 1: [1 1 1 1 1]
Xijm(:,Uns) is called Tony's trick where you actually replicate the
Xijm (vector i guess) 5 times (according to the Uns.) e.g.

I found a matlab script that I want to translate into numpy, but have
difficulties with understanding indexing in matlab. I haven't used
matlab very much and I was hoping that someone could help with the
