Hello everyone,
Was wondering if you could help, I'm a bit of a newbie so this may be a very simple question.
I have a cell array called nodes which contains [1,2,3], [3,4,2,1] and [1,2]
I want to return the position of the vector in the cell array that is length 3 please
Thank you

>> C = {[1,2,3],[3,4,2,1],[1,2]};
>> X = cellfun(@numel,C)==3 % logical index
X =
1 0 0
>> find(X) % linear index
ans = 1

I believe the only way is to loop through the cell array
for k=1:length(c)
if length(c{k})==3
C=c{k};
break;
end
end
