One of the main problems with your approach is that you have forced meta-data into variable names. While this is easy to do by hand, it makes any kind of loop over those variables slow, complex, liable to bugs, and difficult to debug:
Instead of forcing meta-data into variable names, you should note that meta-data is data, and data should be stored in variables (not in variable names). For example your code would be simpler and much more efficient using indexing and simple cell arrays or numeric arrays. Then writing your loop will also be much simpler.
