Something like this should do the job:
slots = 16;
height_row = [];
for i=1:slots
for j = 1:profiles(i)
if length(heights{i,j})==5
height_row = [height_row heights{i,j}'];
end
end
mean_height{i} = mean(height_row,2);
end
I don't really like the double loop, there might be something to do with logical indexing but I can't find my way around it.
Update:
Do this instead :
slots = 16;
for i=1:slots
height_row = heights(i,1:profiles(i));
height_row = height_row(cellfun('length',height_row)==5);
mean_height{i} = mean([height_row{:}],2);
end
though I feel like you want to have the following in the end instead (depending on what you want to do):
mean_height{i} = mean(mean([height_row{:}]))
