For the bugs, maybe not so much, since they do contain a link to the tracker, which is where the patch would be submitted anyway. For the missing functions, it would probably be a good idea.

c2d suggestion[edit]

(control toolbox), this would be very simple to implement as a new choice (now basic choices are bilinear, ZOH I think). Al-Alaoui has introduced a variant of the bilinear/Tustin as follows:

\where 0<=q=<1

The variant just has the additional parts (1+q), (1-q). It would be useful to have an additional call option as follows. Now it's c2d(sys,T,opt) eg Hz=c2d(sys,0.5,'bi') new call would be Hz=c2d(sys,0.5,'alal',0.75) where the last parameter is the "q" seen above. Or could be 'bi2' or whatever. Thanks ...
