% Transform an z-plane transfer function into the s-plane.
If only 3 inputs are given it assumes the input is in transfer
function form. Otherwise it assumes state equation form.
--------------------------------------------------------------------------
Form:
[a, b, c, d] = Z2S( f, g, h, j, dT, sType )
[nums, dens] = Z2SBl( numz, denz, dT, sType )
--------------------------------------------------------------------------
------
Inputs
------
f Discrete state matrix or numerator polynomial
g Discrete input matrix or denominator polynomial
h Output matrix
j Feedthrough matrix
T Sampling period
sType 'bilinear', 'zoh', 'forward', 'backward'
-------
Outputs
-------
a State matrix or nums
b Input matrix or dens
c Output matrix or T
d Feedthrough matrix
