I have a logic as following:

plot_final_iteration_only = true;
for iter = 1 : max_iter
    % Do stuff...
    if (plot_final_iteration_only)
        if (iter == max_iter)
            plotIteration(...);
        end
    else
        plotIteration(...);
    end
end

Is there any way to avoid writing plotIteration(...); for two times (which is a bit redundant for me), but with the same logic?

在 MATLAB Online 中打开

plot_final_iteration_only = true;
for iter = 1 : max_iter
    % Do stuff...
    if ~plot_final_iteration_only || iter == max_iter
            plotIteration(...);
    end
end
