Hi @haeri
The plotting is merely a basic skill that you can learn in MATLAB Onramp. More importantly, you need to know some properties of the exponential decay function before plotting it over the range .
In fact, there is a difference between plotting over and over .
When , .
When , .
x = linspace(0, 5, 1001);
w = exp(-x/0.3042);
plot(x, w), grid on, xlabel('x'), ylabel('w')
w(end) % w(x = 5)
The value of is very small, but it is not absolute zero... yet.
