MATLAB: Given a cell array, find the longest string

Question

Preferably without using loops, I need to find the longest string in a cell array. So with an example array such as the following, in what ways could I go about this? If there are multiple entries with the same length, I need to be able to find both of them.

I'd like to see a way to do it with loops as well.

Answer 1

a={'Pete' 'Townshend1' 'Simmons' 'Steve'  'Sinatra'  'Idaho' 'Sweatshirt'}
val=cellfun(@(x) numel(x),a)
out=a(val==max(val))

%With a loop

for k=1:numel(a)
  val(k)=numel(a{k})
end
out=a(val==max(val))
