I’d be curious to know how many functions we call in total, since if we create a version of python-control that does not require slycot, we’ll have to find replacements for all of those functions. > > -richard > > > On 18 Jun 16, at 00:12, Kangwon Wayne Lee <ka...@gm...> wrote: > > > > Dear Prof. Murray, > > > > I am writing to share one survey on https://github.com/python-control/python-control/issues/27 > > > > I tried to count the number of slycot functions called directly or indirectly by python-control on the 2016 May 31 version of python-control and 2016 March 11 version o fhttps://github.com/jgoppert/Slycot. > > > > I could count 80 functions called. "dcopy" is the most frequently called : 22 times but in slycot functions only. sb02md, sb02mt, sb03md are the most frequently called slycot functions in python-control: all three times each. > > > > One thing to note : function calls are disjoint : no function is called both by python-control and in the slycot functions. > > > > Hope this helps, > > > > KW > > > > -- > > Kangwon "Wayne" Lee > > +82 10 7750 5778 > > > > > -- > Kangwon "Wayne" Lee > +82 10 7750 5778 |
