Creating a fractal using for and if structures

Hi! I'm relatively new at using MATLAB. I'm trying to create a fractal from a given algorithm and this is the code I made. When I run the code I only get an empty plot. Any ideas as to what I'm doing wrong? (I'm sure a lot haha!) I appreicate your help.

m = 2;
n = 1;
hold on
for ii = 1:1000
    q = 3*rand(1);
    if q < 1
        m = m/2;
        n = n/2;
    end
    
    if q < 2
       m = m/2;
       n = (300+n)/2;
    end 
    if i <1000
        plot (m,n)
    end
    hold off
end

plot (m,n,'*')

Hi Emani,

As Walter said you can use this line:

plot (m,n,'*');

to get the point on the plot and if you want all the points you can delete 'hold off' from your code. Then the plot will be as follows:

function func_q26(m,n)
figure(1)
hold on

for i = 1:100000
    q = 3*rand(1);
    if q < 1
        m = m/2;
        n = n/2;
        if i < 1000
            plot(m,n,'.k')
        else
            break
        end
    elseif q < 2
        m = m/2;
        n = (n+300)/2;
        if i < 1000
            plot(m,n,'.k')
        else
            break
        end
    else
        m = (m+300)/2;
        n = (n+300)/2;
        if i < 1000
            plot(m,n,'.k')
        else
            break
        end
    end
end
hold off
