Hi,
How can I use zoom for polar plots ?
I mean a circular cutout would be better than a rectangular cutout.
Nils
from scipy import *
from pylab import show, polar
def M(omega):
s = 1j*omega
return linalg.solve(s*identity(n)-A_0,A_1)*exp(-h_0*s)
A_0 = array(([0,1.],[-32,-2]))
A_1 = array(([0.8,-0.4],[0.16,0.0]))
n = A_0.shape[0]
omega = linspace(-50,50,400)
h_0 = 0.2
for o in omega:
w = linalg.eigvals(M(o))
ind = argsort(abs(w))
w = take(w,ind)
polar([angle(w[-1])],[abs(w[-1])],'b.')
show()
