How to alter Comet Speed

I'm trying to use the comet function as a 2D animation but there does not seem to be an easy way to alter the speed at which it traces, any suggestions?

I don't see a way to control the speed of the comet function. There is a discussion of controlling the speed of an animated line here.

You can alter the comet speed by changing the increment length.

For example, if

t=linspace(0,2*pi,4000);
x=cos(5*t);
y=sin(7*t);
comet(x,y)

then to slow down the tracing speed you can increase the number of intervals, e.g., from 4000 to 40 000:

t=linspace(0,2*pi,40000);

However, it appears that comet speed and increment length are not always proportional. Compare

t=linspace(0,2*pi,1000);

with the first example.

So depending on your desired result, this may work for you.
