set the convergence criteria to be used (i.e. when to stop iterating). in matlab

In MATLAB, you can set the convergence criteria in iterative algorithms by defining a stopping condition based on the difference between successive iterations. Here is an example of how you can set the convergence criteria in MATLAB:

main.m
max_iter = 1000;  % Maximum number of iterations
tolerance = 1e-6; % Tolerance value for convergence

iteration = 1;
converged = false;

while ~converged && iteration <= max_iter
    % Perform one iteration of the algorithm
    
    % Check for convergence using the difference between successive iterations
    if iteration > 1
        % Check the convergence criteria
        if abs(previous_result - current_result) < tolerance
            converged = true;
        end
    end
    
    previous_result = current_result;
    iteration = iteration + 1;
end

if converged
    disp('Algorithm converged.');
else
    disp('Algorithm did not converge within the specified number of iterations.');
end

In this example, the algorithm stops iterating when the difference between the results of two successive iterations falls below a certain tolerance value. The tolerance value determines when the algorithm is considered to have converged. You can adjust the max_iter and tolerance variables based on your specific requirements.
