Hi everybody,
i was wondering, which is the best method to plot a conditional function
within an interval. For example, a function whose values are:
0 if t<t0
f(t) if t>t0
where f(t) is a simple monoexponential decay that starts at t0. I tried
the following in Sage:
t = var('t')
def f(t,t0):
if t<t0:
return 0
else:
return e**(-(t)/tau)
Now if I plot
plot(f(t,t0=0.5,tau=0.05,0,1,rgbcolor='red')
The plot starts at t=0 and unfortunately the function f(t) too!
Is there any better way to define a conditional function with Sage?
Thanks a lot in advance.
Jose.
