How to use a struct array field as input in function

Hi! I'm sorry if this question have already been asked, but I can't figure how to do this.

So here's what I'm trying to do :

I have a struct array with 4 fields inside it

LittlePoney.Blue;

LittlePoney.Purple;

LittlePoney.Green;

LittlePoney.Red;

I would like to create a function which use the field as an input. Like This :

function [A] = BigBrother(Field)

LittlePoney.Field;

end

If someone can help me with this I'd be really happy.

Waiting for your answers Thank you

Look for the term "dynamic field names":

LittlePoney.Blue   = 1;
LittlePoney.Purple = 2;
LittlePoney.Green  = 3;
LittlePoney.Red    = 4;

Field = 'Green';
LittlePony.(Field)
