Periodic function. How would I make this function repeat itself for, let's say, -1 to 3 seconds or something?

clear;clc;
Vm =1 ; % Amplitude of signal T= 1 ; % Period
syms t; 
v1 = Vm*sin((4*pi*t)/T); 
v2= 2*Vm*sin((4*pi*t)/T); 
v = piecewise(0<=t<=T/2,v1,T/2<=t<=T,v2);
figure; 
fplot (t,v) ; 
grid on xlabel('time s '); 
ylabel('Voltage V '); 
title('v(t) vs t '); 
legend('v ')

A for loop could be used. Perhaps something like

for t=-1:3
    % use t in your code
end

That would only give me multiple graphs of the same thing..

well it would be up to you to decide how to use t in your code so that you get a different answer on each iteration of the loop.
