Method parfrac/parfrac


  PARFRAC partial fraction representation of a transfer function.
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
 
  DESCRIPTION: PARFRAC partial fraction representation of a transfer function.
 
                  R(1)       R(2)             R(n)
       H(s)  =  -------- + -------- + ... + -------- + K(s)
                s - P(1)   s - P(2)         s - P(n)
 
  SUPER CLASSES: ltpda_tf < ltpda_uoh < ltpda_uo < ltpda_obj
 
  CONSTRUCTOR:
 
        r = parfrac()                    - creates an empty parfrac object
        r = parfrac(res, poles, dir)     - construct from residuals, poles
                                           and direct terms
        r = parfrac(..., 'name')         - construct including name
        r = parfrac(..., iunits, ounits) - include input and output units
        r = parfrac(pl)                  - create a parfrac object from the
                                           description given in the parameter list.
        r = parfrac(pzm)                 - create a parfrac from a pzmodel.
        r = parfrac(rat)                 - create a parfrac from a rational TF.
 
 
  The poles can be specified in a array or a cell as a real or complex number.
 
  Example:  r = parfrac([1 2+1i 2-1i], [6 1+3i 1-3i], []);
