How to link all points on plot?

I have a small issue, how to link various nonlinear points within loop functions-for example y=0;

for k=1:10

    y=k*2+k^3;

    plot(y,k,'o-');

    hold on;

end

hold off;

The Plot result is as follows. I want to connect all those points. I have little knowledge of interpolations (interp1).

Don't put them in loop....calculate all y at once...

k=1:10 ;
y=k*2+k.^3;
plot(y,k,'o-');

If you want to use loop...See the code...and you can learn few things in looping.

k = 1:10 ;
N = length(k) ;
y = zeros(N,1) ;
k = zeros(N,1) ;
figure
hold on
for i = 1:length(k)
    k(i) = i ;
    y(i)=i*2+i^3;
    plot(y(i),k(i),'o-');   
end
plot(y,k,'b')

My exact code is like this

for k=1:40 (k only for the number of iterations & must be used)

some operation

sp= output values in between 0 and 1

sn= output values in between 0 and 1

plot (sn,sp);

axis([0 1 0 1]);

hold on

end hold off;
