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_cellOperator.m
    path of file: ./repos/chebfun/tests/chebop
    
    the code of the file until where you have to start completion: function pass = test_cellOperator
% TEST_CELLOPERATOR   Test a chebop whose OP is a function that returns a cell

N = chebop(@(r,u) odefun(r,u), [-1 1]);
N.lbc = @(u) [u{1} - 1 ; u{2}];
N.rbc = @(u) [u{1} ; u{2} - 1];
% Need to specify the number of input variables, as otherwise, we won't know the
% number of variables involved:
N.numVars = 2; 
u = N\0;
% Did we get the results expected?
pass = norm(N(u)) < 1e-10 && norm(feval(N.lbc(u), -1)) < 1e-13 && ...

    
function pass = test_cellOperator
% TEST_CELLOPERATOR   Test a chebop whose OP is a function that returns a cell

N = chebop(@(r,u) odefun(r,u), [-1 1]);
N.lbc = @(u) [u{1} - 1 ; u{2}];
N.rbc = @(u) [u{1} ; u{2} - 1];
% Need to specify the number of input variables, as otherwise, we won't know the

    norm(feval(N.rbc(u), 1)) < 1e-13;

    function op = odefun(r, u)
        for n = 1:2
            op{n} = diff(u{n}, 2) + n*u{n};
        end
