I am not able to plot the last loop in my figure with R(xx) figure(1) for xx=1:5; plot(R(xx),'--'); end .What is the issue with plotting the data from the curve fit? How do I solve it?

     figure,
     for xx=1:5;
       plot(R(xx),'--'); % Is it plot with one variable only?
       hold on;
     end
