p = poctave(x,fs) returns the octave spectrum of a signal x sampled at a rate fs.

The octave spectrum is the average power over octave bands as defined by the ANSI S1.11 standard [2].

You can see the detail here.

Plus, if you want to learn the function, you can use document command.

It is very useful.
