Hi all
For the below code, I'm trying to set up a series where instead of just the most recent value of k, it increases the size of the matrix every time it runs, so it would be Xt = [ones(t-h+1,1), Lt*yt, Lt^2*yt, ... Lt^k*yt]
for k = 1:p
Xt = [ones(t-h+1,1), Lt^k*yt];
end
I know this code will only use the most recent value of k, so how would I be able to create it the way I described before? I'm pretty new to coding in general so apologies if this is a silly question.

I don't know what size any of these are, nor what the goal is.

To my understanding, you want to set up a repeating series of terms so that,
Xt = [ones(t-h+1,1), Lt*yt, Lt^2*yt, ... Lt^k*yt].
Here is a possible workaround:
cat = [];
for k = 1 : p
cat = [cat, Lt^k*yt];
Xt = [ones(t-h+1,1), cat];
end
