MATLAB: 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;

Your plotting code is trying to select just one element from the t and y vectors.
I think you want this instead:
