sw_array and time_int

Hello, can you explain to me exactly what operations the sw_array and time perform in this code? Also, why does sw_array have 13 columns? And can you give me some examples of the mathematical operations represented by sw_array(:,:,2) = [0 1 0 1 1 1 1 1 1 1 0 1 0]? I've been struggling with understanding the code for the past three weeks, but I couldn't grasp it. Thanks in advance.

Best regards.

a = M;
n = Sector;

t1 = a*Ts*sin(n*pi/3 - angle);
t2 = a*Ts*sin(angle - ((n-1)*pi/3));
t0 = Ts - t1 - t2;
tsh = D*Ts;

I have no idea what sw_array is or why it is defined with 13 columns. Eveidently it will take on 13 y values for the second dimension.

I suggest you ask whoever wrote the code. But that's so obvious that I'm assuming you spent the last 3 weeks trying to contact them and they refuse to answer. So then I have to wonder, if you don't know what the code does, then why do you want to use it?

I am in the final stage of my doctoral study, and completing this will mark its culmination. I am very close to finding the solution, yet equally far away at the same time. :D Unfortunately, the authors of the code haven't provided any feedback, and I don't have any other simulation to proceed with apart from this code.
