you are NOT allowed to do this...

I suspect your code is over-complicated and not properly using the Matlab language. Re-read the Matlab documentation and re-think your approach. To spell out the exact solution to what you're trying to do (but possibly shouldn't be doing):

for i = 2:6
tmp=sprintf('UM0%d',i);
UM.ET.hh0i = UM.(tmp).L4(:,17);
end

you could also have done the slightly more explicit-looking:
tmp=['UM0',num2str(i)];

This (tmp) notation is described in the Matlab help under the section dealing with structures.
