Errors in control toolbox demos

[Raimund Dold]

Hi,

I downloaded and compiled octave-2.1.33 and tried some of the examples and 
got some erros:

- frdemo -> 1 -> 1 and after some returns I get the following error:


zero-pole form:
10 (s - 1)
-----------------
  (s + 1) (s + 5)
 
The bode plot command is identical to the tf form:
Command: bode(sys2);

- hinfdemo -> m -> y (plot the step responses) I get the following error:

Is this the right place to report this errors?
