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.

Hi,
I needed to write 2D Ising model simulation into my school and I
decided to compare the two possible solutions how to do it, so I of
course wrote
it in Python, then rewrote it in Fortran + f2py, and also Cython. What
is better? Read below. :) But for the impatient, I am going to use
Cython, r

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
following:
It says:
Uns = ones(1,m);
... and then later
Xijm(:,Uns)
