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

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
