Does OCTAVE have capabilities to manipulate a rational function (i.e. a

Well, GNU Octave knows IEEE arithmetic, and you can easily write a
script or function file that returns the values of a rational function
at a given point...

But if what you want is to symbolically manipulate rational functions,
then Octave probably isn't the right tool for the job. Try Maxima or
Axiom for that.

Is there any OCTAVE function to provide a variable-substituted
rational/polynomial function of P(s) with "s" substituted by e.g. "j*f" or

There are hacks to accomplish this sort of behaviour, but it sounds
like you want symbolic manipulations. Octave is not made for this.
