How can I graph all the values of n in the while loop ? Theres my program.

 n=input('Enter a natural number');

 cont=1:1:n;

 while n>1

    if rem(n,2)==0
       n=n/2;

    elseif rem(n,2)~=0      
       n=n*3+1;

    end
 plot(cont,n,'--rs');        
 end

Something like this? Not quite sure what you want your x-axis to be.

 n = input('Enter a natural number');

 cont=1:1:n;
 ii = 0;
 while n>1
    ii = ii + 1;
    if rem(n(ii),2)==0
       n(ii+1) = n(ii)/2;
    elseif rem(n(ii),2)~=0      
       n(ii+1) = n(ii)*3+1;
    end

 end
 plot(ii,n,'--rs');

The hold on will give me the points but how do i conect them, in other words i want a single line plot.

[Mischa Kim]

Right. Like the one created by the code above?

Or you might want to use

 plot(sort(n),zeros(size(n)),'--rs');

[jonathan garcia]

% i used hold on and in the plot only appears the points because hold on is used to unite different % plots in one, so i guess that im unable to create a line to connect the points.

n=input('Enter a natural number');

cont=1;

while n>=1

plot(cont,n,'rs','LineWidth',2,'MarkerSize',10);

    if n==1
        n=1;break

    elseif rem(n,2)==0
       n=n/2;

    elseif rem(n,2)~=0      
       n=n*3+1;

    end

hold on cont=cont+1; end

jonathan, have you checked out/run the code that I posted above?

My second post contains another way of plotting the data you might want to try.
