MATLAB: How to subplot two or more multiple-plots created by different loops

plotting

Hi,
I am trying to create a subplot(2,1), but I do not know how I should use this function when I have two plots created by differents loops. Here the code without subplot:
 clear all; clc;
 n=input('The value of n is:');
 k=100;
 X1=linspace(-20,20,k);
 X2=linspace(-1,1,k);
 M=zeros(n,k);
 N=zeros(n,k);
 figure(); hold on
 for i = 1:n
    plot(X1,besselj(i,X1));
    legendInfo{i} = ['n = ' num2str(i)];
 end
 legend(legendInfo)
 title('Bessel')
 xlabel('X')
 ylabel('Y')
 hold off
 figure(); hold on
 for i = 1:n
   plot(X2,legendre(i,X2));
   legendInfo{i} = ['n = ' num2str(i)];
 end
 legend(legendInfo)
 title('Legendre')
 xlabel('X')
 ylabel('Y')
 hold off
My question is: Where I put the subplot function? I have tried and the only thing that I get is error.
Thank you very much.
Have a nice day.

Please put it just before 'plot' function, like:
n = input('The value of n is:');
k = 100;
X1 = linspace(-20,20,k);
figure
for kk = 1:n
  subplot(n,1,kk)
  plot(X1,besselj(kk,X1));
  legend(['n = ' num2str(kk)])
  if kk == 1
      title('Bessel');
  end
  xlabel('X')
  ylabel('Y')
end
