hi, I'm new to struct Arrays and I've got the following problem:
filelist(:).names = upper(filelist(:).names);
somehow I cannot figure out how to tell matlab to assign each result of the upper function to one entry in the filelist. I'm sure that there's a simple solution but I understand how until now
Thanks!

filelist(1).names='a';
filelist(2).names='b';
a=upper({filelist.names});
[filelist.names]=deal(a{:})

for j1 = numel(filelist):-1:1
filelist(j1).names=upper(filelist(j1).names);
end
variant with arrayfun and others
filelist = ...
cell2struct(arrayfun(@(x)upper(x.names),filelist,'un',0),fieldnames(filelist));

Is there also a solution avoiding the loop?

less lines, nicer code and isn't it often faster to use vecorization (if possible)
anyway thank you very much for your nice answers!
