If I had an array of angles (the phi value), and I wanted to use them to plot m against iterations of the simulation (N) (as shown in the attached image), then how do it?
I tried this before but since the angles are in an array and I'm trying to add all of them together and multiply them by 1/N, I can't seem to be able to plot them.
I think I need to make an array for the m values to them lnspace and plot against N, but I've not had much success in getting it to work.
Sorry for the poor explanation.

Are there N phi values or is the division by a value that is unrelated to the number of phi values?

Let theta be an N by number_of_angles array (so each row refers to a different time step)
m_temp = sum(cos(theta),2);
At this point, you need to decide whether the division is by the number of iterations that had occurred up to that point, or if it is by the total number of iterations. If it is by the total number of iterations, then
m = m_temp / N;
plot(m)
If it is by the number of iterations to that point, then
m = m_temp ./ (1:N);
plot(m)
