[python-control-developers] Some questions

[SUPSI <rob...@su...>]

Hi

I've been requested by the "Schweizerische Gesellschaft fuer Automatik" 
to write a tutorial about python for control system for all the Swiss 
university professors.

By writing some examples for the tutorial I've found some little problems:

Here are the firsts:

1) "rlocus" creates automatically a vector with the k values, if not 
provided. "root_locus" should have the possibility to pass kvect=None, 
but it is not accepted (-> error). It can be simply solved by adding the 
same lines as in rlocus, before finding a better algorithm to get the k 
values

     #! TODO: update with a smart calculation of the gains using sys 
poles/zeros
     if klist == None:
         klist = logspace(-3, 3)

2) "bode" and "bode_plot": in my opinion the flag dB=True should be the 
default choice (but this is only my opinion...)

Best regards
