FResp:
-------------------------------------------------------------------------------
Compute the frequency response of the system
.
x = ax + bu
y = cx + du
for the input vector iu, and output vector iy. If no output arguments
are given it will automatically display Bode plots for all channels.
If only 1 output is requested, the complex values will be output.
-------------------------------------------------------------------------------
Form:
[mag, phase, w, io] = FResp( a, b, c, d, iu, iy, w, uPhase, pType )
[mag, phase, w, io] = FResp( num, den, w, uPhase, pType )
-------------------------------------------------------------------------------
------
Inputs

c Measurement matrix
d Input feedthrough matrix
iu Inputs ( = 0, or leave out for all)
iy Outputs ( = 0, or leave out for all)
w (1,:) Frequency vector
uPhase (1,:) Unwrap phase = 'wrap' to wrap it within 180 deg
pType (1,:) 'bode' or 'nichols'
-------
Outputs
-------
