Re: [python-control-discuss] Frequency response data object

[Richard M. <mu...@cd...>]

Hi Rene.  Let me try to have a quick look at the branch today or tomorrow, then I can send you a note and we can work on the merge.  

There have been some changes since 0.5c (we are now at 0.6a) that may make the integration a little bit "interesting".  The main one is the "timebase" class variable 'dt', used to distinguish discrete and continuous time systems.  In addition, I have been doing small changes throughout to try to make things more compatible with python 3.

Also (for everyone on the list): I'm going to re-establish the commit-hooks so that e-mail goes to this list when changes get committed to the repository.

I'll send you an e-mail after I have had a look.
