Loop over variables with just a number in the name different

Hello, I have a number of vectors: WD.Tair1 WD.Tair2 WD.Tair3 WD.Tair4

I would like to loop over them and each time return me the seventh number in each of them. How can I do this? Be aware that the vetors are not of the same lentgh.

Period = 1;
for Period = 1:4 %loop over all different time periods
    T0 = WD.Tair???(7);

end

I hope you get it. Thanks

In your case, use dynamic field names.

for Period = 1 : 4
  fn = sprintf('Tair%d', Period);
  T0 = WD.(fn);
  ....
end
