% 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
