bode() returns only phases in interval +/- 180°

6

If I want to determine the phase at some frequency using bode(G, w) with w as a 1-element vector, bode() only returns values in the interval (-180°, 180°). This is...

Building a vector of both continuous and discrete

Noticed that plotting by sending in a vector of plots does not seem to work when there is a mix of discrete and continuous, but when sending them in one...

Zygote.jl does not handle try-catch, so I modified `feedback` slightly to avoid using it, but maintained the useful error messagees. The comment `# inv seems to be better than lu`...

``` h = 0.1 z = tf("z", h) sp = 2/h * (z-1)/(z+1) sys = (1+sp)/(1+sp/10)^2 bodeplot(sys) ``` This does not manage to plot correctly, while it does in matlab....
