Does anybody have Octave code to draw Rayleigh fading envelope?

Ah, probably is a method for synthetic generation of a time trace of
fading.  I know there are some methods, but I have not the details.

If it's short, you can try to post it here, and maybe someone will be so
kind to translate it into Octave.
