Iterating over a list of strings in MATLAB

Date: 2022-07-05 10:35:31

I'm trying to iterate over a list of strings in MATLAB. The problem is that, inside the 'for' loop, my iterator is considered a 'cell' rather than a string. 

 

for str = {'aaa','bbb'}
  fprintf('%s\n',str);
end  


??? Error using ==> fprintf
Function is not defined for 'cell' inputs.

What is the correct\elegant way to fix this?

  fprintf('%s\n',str{1});
end

Here's a more sophisticated example on printing contents of cell arrays.
