good morning, I have acell array and i want to compare cell's length. Till now I used just t compare the equality of the cells using:
isequal(A{1,:})
A is the cell array.
I tried to run
isequal(length(A{1,:}))
but that's not correct.
What is the easiest way to achieve that, without using a or cycle???
Thanks

This is easy to do in one line using cellfun , diff and any:
>> A = {cell(1,3),cell(1,3),cell(1,3)};
>> B = {cell(1,5),cell(1,2),cell(1,9)};
>> any(~diff(cellfun(@numel,A)))
ans =
1
>> any(~diff(cellfun(@numel,B)))
ans =
0

A hint based on some guessing
cac = {'abc','def', 'ghi'};
tmp = cellfun( @length, cac, 'uni', false );
isequal( tmp{:} )
returns
ans =
1
I failed to make a one-liner
&nbsp
Addendum
A variant more in line with the comments to the question
cac = {'abc','def', 'ghi'};
cac = { cac, cac, cac };
tmp = cellfun( @length, cac, 'uni', false );
isequal( tmp{:} )
returns
ans =
1

sorry, what stands 'uni' for? just as an example of length?
