How to label answers from a function you called in a script?

When i call the ODESystemSolver i get two answers back. But how can i label them in the code. Basically need those two answers to input them into my secant method function to get a new approximations then repeat the step. i added a picture of what im trying to do i hope its understandable. Sorry for long question

You just want to pass your functions to SecantMethod if i understood your correctly

Type this in the main script

syms x1(t) lambda1(t)
x1(t) = ODE.x;                % get solution functions
lambda1(t) = ODE.lambda;
t = linspace(0,2);            % time span
x0 = x1(t);                   % numeric solution
l0 = lambda1(t);
    % pass values to SecantMethod
for i = 1:length(t)-1
    lam1 = SecanthMethod([x0(i:i+1); l0(i:i+1)]);
    if lam1 what?
        break
    end
end
