Plot function is not working

I'm having problem plotting some function from my homework assignment. I created a code similar in structure to what I am trying to do. Same problem, the graph is not showing. Do you guys have any clue what to do here?

The code is given as follows:

n = 1;
h = 0.05;
t(n) = 0;
y(n) = 0;
while t(n)+h < 8
    y(n+1) = pi^(-n^2);
    t(n+1) = t(n) + h;
    n = n + 1;
end
plot(t(n),y(n))

Your plotting code is trying to select just one element from the t and y vectors.

I think you want this instead:

plot(t,y)

(I changed my answer a bit after your edit.)

I tried with homework question that had similar problem, and it worked! Thanks!
