Loading required packages

Before running any of the code presented in this tutorial, you should copy-paste the following into the ipython command prompt

from numpy import * # package for numerical calculations
from pylab import * # package for graphics
from control import * # package for control theory calculations
from control.matlab import * # package for control theory calculations
ion() # display graphics automatically

Test

Copy-paste the following into the ipython command prompt (after having loaded the required packages as recommended above)

sys = tf([1, 0], [1, 2, 5])
rvect, kvect = rlocus(sys, klist = arange(0, 10, 0.001))

If you see errors such as unknown locale: UTF-8, then exit ipython, copy-paste the following in your terminal, and run ipython again

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
