I don't know if this is a developer question or not. It isn't
anything hard core developer-ish, so I will start with the regular
list.
I would like to propose the addition of the following methods to
signal.ltisys.lti. The two lsim ones are just conveinence functions,
but I find the Bode method really useful.
(I may have had to add an import statement for poly1d).
def Bode(self,f):
num=poly1d(self.num)
den=poly1d(self.den)
s=2.0j*pi*f
tf=num(s)/den(s)
return tf
def lsim(self, U, T, X0=None, interp=1):
Y=signal.lsim(self, U, T, X0, interp)
return Y
def lsim2(self, U, T, X0=None):
Y=signal.lsim2(self, U, T, X0)
return Y
Basically, I am teaching a class with some controls/systems modeling
and want Python to offer most of the same tools for lti's as Matlab's
controls toolbox (eventually).
Any thoughts?
