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: fastLICFunction.m
    path of file: ./repos/PIVlab
    
    the code of the file until where you have to start completion: function [varargout] = fastLICFunction(varargin)

% AUTOCOMPILE compile the missing mex file on the fly

% remember the original working directory
pwdir = pwd;

% determine the name and full path of this function
funname = mfilename('fullpath');
mexsrc = [funname '.c'];
[mexdir, mexname] = fileparts(funname);

try
% try to compile the mex file on the fly

    
function [varargout] = fastLICFunction(varargin)

% AUTOCOMPILE compile the missing mex file on the fly

% remember the original working directory
pwdir = pwd;

% determine the name and full path of this function
funname = mfilename('fullpath');
mexsrc = [funname '.c'];
[mexdir, mexname] = fileparts(funname);

try
% try to compile the mex file on the fly
disp(['trying to compile MEX file from ' mexsrc ' ...']);
cd(mexdir);
mex(mexsrc);
cd(pwdir);
success = true;

catch
% compilation failed
disp(lasterr);
error('could not locate MEX file for %s', mexname);
disp(['Please try to compile the file ' mexsrc ' manually.']);
disp('You might need to run "mex -setup" in Matlab before compilation');
cd(pwdir);
success = false;
end
