Help writing and solving a problem

I'm having a hard time with this problem regarding ideal diode and voltage. I am given the voltage across load

VL=

vs if vs > 0 | 0 if vs <=0

Supply voltage is given by:

vs(t) = 3e^(-t/3)sin(pi*t)

I have to plot VL versus t for 0 <= t <= 10

I've tried using a for loop but I can't get it figured out.

Can someone help?

VL = vs;
VL(vs < 0) = 0;

I'm confused though cause any number from 0 to 10 you plug into the vs equation it turns out to be 0. How would I write this up

[Walter Roberson]

That's because you are using only integer t . sin(pi times an integer) is always 0.

So wouldnt the plot just be a straight line at 0?
