Plotting a periodic signal

Hello guys ! I would like to ask you some questions about plotting a periodic signal. I have the following signal:

I represented it on 37 periods . I would like to represent on 37 periods, the signal y2 with the property:

For y1 i have T1 = 0.5, for y2 T2=1, y3 T3=2.

How can i change the period of my signal in the following code ? Or should i write it otherwise ?

Thank you !

This is my code for y1:

%y1(t) 
T_1 = 0.5;
t = linspace(0,1,100);
x = 0.86*t.^2-2.05*t+0.97;
v = ones(1,37*2);
for i=1:37*2
   if mod(i,2) == 1
       v(i)=-v(i);
   end
end
y1 = x(:);
y1 = y1*v;
y1 = y1(:);
T1 = linspace(0,37,3700*2);
figure(2);
plot(T1,y1,'r','LineWidth',1.5);
grid on;
grid minor;
xlabel('t[ms]', 'fontweight', 'bold', 'fontsize', 16, 'FontName', 'Times New Roman');
ylabel('y_{1}(t)','fontweight','bold','fontsize', 16, 'FontName', 'Times New Roman');
title('Reprezentare grafica a semnalului y_{1}(t) pe 37 de perioade','fontweight','bold','fontsize',16, 'FontName', 'Times New Roman');

You define T_1, but never use it in your code. I don't know what your result should look like, but the most obvious place to incorporate your period is in your code to create t.

T_1 = 0.5;
t = linspace(0,2*T_1,100);

You should then be able to just adjust the value of T_1 and the rest of the code should adjust accordingly.
