How to save output?

x=[0:n-1];

y=[0:n-1];

figure

for i=1:5

for j=1:5

if rem(((y(j))^2)-((x(i))^3)-2*(x(i))-3,5)==0

plot(x(i),y(j),'r o');

hold on;

end

end

end

grid;

hold off;

How can I save output of loop ? For example in this case I have 6 points (1, 1),(1, 4),(2, 0),(3, 1),(3, 4),(4, 0), how can I save it?

Try this:

n = 10;
x=[0:n-1];
y=[0:n-1];
k = 0;                                                          % <- ADD
figure
for i=1:5
    for j=1:5
        if rem(((y(j))^2)-((x(i))^3)-2*(x(i))-3,5)==0
            k = k+1;                                            % <- ADD
            xy_mtx(k,:) = [x(i) y(j)];                          % <- ADD
            plot(x(i),y(j),'r o');
            hold on;
        end
    end
end
grid;
hold off

The results are saved in ‘xy_mtx’.
