You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: mne_ex_data_sets.m
    path of file: ./repos/spm/external/mne
    
    the code of the file until where you have to start completion: function [res] = mne_ex_data_sets(fname)
%   
%   Find all evoked response data from a given file
%
%   [res] = mne_ex_data_sets(fname)
%
%   fname   - Name of the file to look at
%   res     - Structure containing the result
