I have a cell each cell storing a different sized array. How do i find the largest width and height of all the arrays ?
I tried
size(test{:}(:,1,1))
test is my cell. so meaning for all test, find the size of (:,1,1). But it is wrong of coz so help me thanks.
Like
cell{1} = 10x10 uint8
cell{2} = 10x11
cell{3} = 5x99
so
min_size_of_cell_array(cell{:}) = 5,10
like that

>> C{1} = NaN(10,10);
>> C{2} = zeros(10,11);
>> C{3} = ones(5,99);
>> cellfun('size',C,1) % rows
ans =
10 10 5
>> cellfun('size',C,2) % columns
ans =
10 11 99

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

Try this:
% Create our data, a cell array of vectors of random lengths.
for k = 1 : 100
thisLength = randi(50); % Anywhere from 1 to 50.
ca{k} = rand(1, thisLength); % Create row vector of this length.
end
% Now that data has been created,
% find the lengths of all the elements.
allLengths = cellfun(@length, ca)
% Now find the longest vector between element 15 and 35 (for example)
maxLength = max(allLengths(15:35))
