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: mff_setup.m
    path of file: ./repos/fieldtrip/external/egi_mff_v2
    
    the code of the file until where you have to start completion: function mff_setup

    
function mff_setup

% MFF_SETUP ensures that the JVM is available and that the MFF java
% implementation is on the java classpath.

% this toolbox requires JAVA to be running and properly configured
if ~usejava('jvm')
  error('the EGI_MFF format requires that the java virtual machine is available, see http://www.fieldtriptoolbox.org/getting_started/egi')
end

% check that the java archive (jar file) is on the path
% the user can add it to the static path using classpath.txt
if ~(exist('com.egi.services.mff.api.MFFFactory', 'class')==8)
    jarpath = fullfile(fileparts(mfilename('fullpath')), 'java', 'M*.jar');
    jarlist = dir(jarpath);
    if size(jarlist, 1) == 1
        
        % Some MATLAB versions have a bug in javaclasspath that causes global
        % variables to be erased. Hence we keep a local copy and restore it afterwards.
