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_license.m
    path of file: ./repos/malini/Codes/deconvolution - model/spm8/external/mne
    
    the code of the file until where you have to start completion: function mne_license


    
function mne_license

% MNE_LICENSE prints the license only once upon the first call to
% this function. If the user does a "clear all", the license will
% again be shown.  This function should be included in every openmeeg
% function to ensure that the license is displayed at least once.
