Please help me make this function periodic

Thank you very much for all the help!

T = 1 millisecond

Vm = 1 volt (amplitude voltage)

t = linspace(-T, 2*T, 3001)

The following pararameter is given

v(t) = Vm - (Vm/T)t for 0<= t <= T

0 elsewhere

I need to modify the vector v so that is represents a periodic function with a period T over this time period

(hint: it should look like a sawtooth), and plot v vs t over the range from -T to 2T.

So far I have this:

T = 1;

Vm = 1;

t = linspace(-T,2*T,3001);

for i = 1:length(t)

if (t(i) >= 0) && (t(i) <= T)

v(i) = Vm - (Vm/T)*t(i);

else

v(i) = 0;

end

end

plot(t,v)

You can repeat copies of an array along any dimension using the 'repmat()' function. This will allow you to generate a periodic function. The following link contains the documentation for the same:

In addition, refer to the following MATLAB answer link which has a query of the same nature as the one you've asked. Go through the accepted answer.

Write a function for that pulse shape, then have a look at the pulstran function.
