Hi
Given for instance I have a struct as follows:
s(2) = struct('name','anna','age',18)
s(1) = struct('name','bernd','age',22)
Now I want to change all the names to 'unknown', i.e. as well for s(1) as for s(2). How can I do it (this is just a toy example, I do have a 123 dimensional struct where I do not want to do it one by one). Thanks

Hi,
without a loop:
[s.name] = deal('unknown')

s(2) = struct('name','anna','age',18)
s(1) = struct('name','bernd','age',22)
n=numel(s)
for k=1:n
s(k).name='unknown'
end
