SYNOPSIS

DESCRIPTION

FOTF Creates a new fractional-order transfer function object

Usage G = FOTF(A, NA, B, NB, T)
      G = FOTF('s')
      G = FOTF(BPOLY, APOLY, T)
      G = FOTF(H)

where G,H          - FOTF objects,
      A, NA, B, NB - vectors containing pole polynomical coefficients and
                     exponents and zero polynomial coefficients and
                     exponents respectively.
      BPOLY, APOLY - polynomial strings, e.g. 's^0.5+1e3', '1-5s^0.75'.
      T            - input/output delay [sec]
