for idx = 1:length(alfiles)
if contains(alfiles(idx).name,'tx01')
v=v+1;
temp(v)= alfiles(idx);
thsi is where the issues comes up - my alfiles are not always going to be of size 3 - in may bes less or more - how may i modify it
if v ==3
[~, index] = max([temp.datenum]);
files(1) = temp(index);
end
elseif contains(alfiles(idx).name,'tx02')
v=v+1;
temp(v)= alfiles(idx);
if v ==6
[~, index] = max([temp.datenum]);
files(2) = temp(index);
end

If you want to test whether v is equal to the number of elements in alfiles, why don't you test that instead of hard-coding 3? Or is your question how to prevent the test if the number of elements is more than 3?
What do you want to happen?

You should make it a habit to use numel instead of length. Calling length is equivalent to max(size(A)), which is almost never what you want.

Thank you, that is a great advise! after reading about numel it sure does help in preventing few of the issues i have had by using max and size......great catch!
