CButter:
-------------------------------------------------------------------------------
Build a continuous Butterworth Filter with output of the form
dx/dt = ax + bu
y = cx + du
If no outputs are specified it will plot the frequency response
-------------------------------------------------------------------------------
Form:
[a, b, c, d] = CButter( n, wC, tSamp, sType )
-------------------------------------------------------------------------------
------
Inputs
------
n (1,1) Order
wC (1,1) Cutoff
tSamp (1,1) Sampling frequency
sType (1,:) State equation type ('Delta' or 'Z')
-------
Outputs
-------
a State transition matrix
b Input matrix
c Measurement matrix
d Feedthrough matrix
