any simplified way to get the length of each variable in structure

Hi:

I have a structure, each element of the structure has a different size, which is what I neede.

it is very easy to write a for-loop to get it, but I want know if there is any easier way?

Please see attached test file, and below is the test code:

for i=1:1:length(test)
sz(i)=length(test(i).a);
end

Bests,

Yu

sz = arrayfun(@(t) length(t.a), test);

Answer 2

arrayfun(@(x)length(x.a),test) % use numel if the variables are a vector , I didn’t download your file so not sure how your variables are but this seems to do what you want.

Thank you all the same.
