Running R2019A with Parallel toolbox and I'm testing it using fthe parfor tutorial. How do i get the solveVdp file to be available?

>> D = parallel.pool.DataQueue;
D.afterEach(@(x) updateSurface(c, x));
>> parfor ii = 1:numel(N)
[t, y] = solveVdp(N(ii), M(ii));
l = islocalmax(y(:, 2));
send(D, [ii mean(diff(t(l)))]);
end
Starting parallel pool (parpool) using the 'local' profile ...

Connected to the parallel pool (number of workers: 12).
Analyzing and transferring files to the workers ...done.
An UndefinedFunction error was thrown on the workers for 'solveVdp'. This might be
because the file containing 'solveVdp' is not accessible on the workers. Use
addAttachedFiles(pool, files) to specify the required files to be attached. For
more information see the documentation for 'parallel.Pool/addAttachedFiles'.
Caused by:
Undefined function 'solveVdp' for input arguments of type 'double'..
