SYNOPSIS

function [num, den, q] = tfdata(G)

DESCRIPTION

TFDATA Fractional-order transfer function data

 Returns numerator and denominator of a fractional transfer function in a
 rational transfer function form with commensurate order q

 Usage: [NUM, DEN, Q] = TFDATA(G)

 Note, that vectors of 'double' type are returned.
