MATLAB: How we can control the length of each elemnts in a cell array

cell arrayelemntlength

Dea All, I'm wondering how we can control of the length(size) of each elemnt in a cell array(Since each elemnt is a matrix itself) .

Thanks

C - your cell array

out = cellfun(@size,C,'un',0)

C = arrayfun(@(x)rand(randi([1 20],1,2)),(1:8)','un',0);% example
[s,d] = cellfun(@size,C);
out = max([s,d]);

s1 = size(A1);
s2 = size(A2);
s22 = max(s1(2),s2(2));
A = [A1,zeros(s1(1),s22 - s1(2));A2,zeros(s2(1),s22 - s2(2))];
