It’s not clear to me what you want.

See if this works for you:

t = linspace(0, 2*pi, 250);
s = sin(t.^2);
figure(1)
plot(t, s)
grid

Ok thanks, that works but this is what I should have asked t = linspace(0, 2*pi, 250); s = (t.^2);

figure(1) plot(t, s) grid

So I've removed sin. it plots the correct signals but I need to repeat so it makes peaks,

That is straightforward to do:

t = linspace(0, 10*pi, 500);                % Time Vector For 5 Cycles (5 * 2*pi)
tm = rem(t,2*pi);                           % Calculate ‘t mod(2*pi)’
s = @(t) t.^2;                              % Create Anonymous Function For Convenience
figure(1)
plot(t, s(tm))                              % Plot
grid
