Thank for John W. Eaton

 [ 3] Frequency response functions
 [ 1] Continuous system bode analysis
for  Bode analysis and  Nyquist analysis
goes well for 2.9.17 on cygwin and octave.

However for Discrete system seems not to worked well.
This is for both cygwin and mingw.
For 2.9.16, both worked well.

I aplogoze for seprated reports.

**************
For 2.9.17 cygwin octave.
Discrete system bode analysis

Display bode plots of a discrete SISO system (dbode)

Example #1, Consider the following discrete transfer
 function:

sys1 = tf([0.00100502, -0.00099502], [1, -2, 1], 0.001);
sysout(sys1)
Input(s)
      1: u_1

Output(s):
     1: y_1 (discrete)


Invalid call to disp.  Correct usage is:

 -- Built-in Function:  disp (X)


Additional help for built-in functions and operators is
available in the on-line version of the manual.  Use the command
`doc <topic>' to search the manual index.

Help and information about Octave is also available on the WWW
at http://www.octave.org and via the address@hidden
mailing list.
