IndexError: index -1 is out of bounds for axis 0 with size 0 #1014
Description
I get this:
Traceback (most recent call last):
File "C:\Users\me\PycharmProjects\f\control1.py", line 17, in <module>
S = ct.step_info(sysdata=y_out2, T=T2)

settled = np.where(
IndexError: index -1 is out of bounds for axis 0 with size 0
From this: (just a simple integrator TF)
import control as ct
import numpy as np
num = [0,5]
den = [1,0]
H = ct.TransferFunction(num, den)
t = np.arange(start=0, stop=2, step=1/120)
T2, y_out2 = ct.timeresp.impulse_response(sys=H, T=t)
pyplot.figure(1)
pyplot.plot(T2, y_out2)
pyplot.grid(True)
pyplot.show(block=False)
S = ct.step_info(sysdata=y_out2, T=T2)
