% Transform an s-plane transfer function into the z-plane. If only 3 inputs are given it assumes the input is in transfer function form. Otherwise it assumes state equation from -------------------------------------------------------------------------- Form: [numz, denz, k] = S2Z( nums, dens, dT, sType ) [f, g, h, j] = S2Z( a, b, c, d, dT, sType ) -------------------------------------------------------------------------- ------ Inputs ------ a State transition matrix or Numerator polynominal b Input matrix or dens c Output matrix or T d Feedthrough matrix T Sampling period sType bilinear', 'zoh', 'forward', 'backward' ------- Outputs ------- f Discrete state matrix or numerator polynomial g Discrete input matrix or denominator polynomial h Output matrix or gain j Feedthrough matrix -------------------------------------------------------------------------- References: Franklin, G.F., J.D.
