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: test_followpath.m
    path of file: ./repos/chebfun/tests/chebop
    
    the code of the file until where you have to start completion: function pass = test_followpath(~)
% Test the path following capabilities of Chebfun. This is not extensive, mainly
% checking nothing crashes in basic mode.


    
function pass = test_followpath(~)
% Test the path following capabilities of Chebfun. This is not extensive, mainly
% checking nothing crashes in basic mode.

% Initialize a false pass vector
pass = zeros(1, 4);


%% Test Bratu problem
N = chebop(@(x,u,lam) diff(u,2) + lam*exp(u), [0 1]);
N.lbc = @(u,lam) u;
N.rbc = @(u,lam) u;
lam0 = 0.01;
% Call method, no plotting, no printing
try
    [u, lamvec] = followpath(N, lam0, 'maxstepno', 6); %#ok<*ASGLU>
    pass(1) = 1;
catch ME
    rethrow(ME)
end
