Create a list of list and take the mean

Hi everyone
I am new to Matlab (I came from a Python background).
I have a question about creating a list of arrays and calculating their componentwise means. I know how to this in python using numpy array. I tried to apply the same logic in Matlab but somehow it does not work.
Please find below one example. I want to calculate the componentwise mean of aps. Perhaps, I used the wrong data structure for the aps?
Thank you very much.
aps = {};
for i = 1:length(locs)
aps{i} = [i i+1 i+2];
end

mean(vertcat(aps{:}),1)

That makes sense. My understanding is that the function cell2mat and vertcat transform the aps into a 2D-array. Once it is done, we can calculate the mean on one of the axes. This is similar to Python. Thank you both!
