ND2SS:

--------------------------------------------------------------------------
   Creates state-space model from numerator and denominator polynomials.

   Creates state-space model given a denominator polynomial and
   a set of numerator polynomials. The state-space model will be
   of the form
   .
   x = ax + bu
   y = cx + du

   where each row of C corresponds to a row of num. The output is in
   terms of phase variables, also known as the control canonical form.

   Since version 1.
--------------------------------------------------------------------------
   Form:
   [a, b, c, d] = ND2SS( num, den )
