Access the fields in a structure array specified in a list of strings.

I have a lot of numbers stored in a massive structure, and I need to access specific fields. So a minimal example, let say I have:

X.puppy=7;
X.kitten=4;
X.duckling=2;

and I want to access these fields:

furry={'puppy','kitten'};

Is there a way to do this without a loop?

I don't care what the format of the output is since I can easily convert, I just need something that outputs: [7 4].

Thanks for any help in finding my X.(furry).

Try this:

X.puppy=7;
X.kitten=4;
X.duckling=2;
furry={'puppy','kitten'};
% Convert to table
t = struct2table(X)
% Extract numbers.
out = t{1, furry(:)}

Thank you. The day has come where I appreciate tables! It's possible that they're a more natural option for my data storage in the first place, I'll have to think about it.
