Thank you very much. The last suggestion works very well! Do you also happen to know how to construct the C = { A1 , A2, ... A100 } struct, without hardcoding the number of elements? At the moment I have 4 elements, so C = { A1, A2, A3, A4 }; However, the number of elements depends on other variables in my script, which I would like to be able to change. How could I program C so that is flexible like that? I hope it is clear what I mean.
