Example of using matlab to plot root-locus for system with characteristic equation 1 + K(s+1)/(s2 + 4s + 8) = 0.
Matlab commands typed:
>> rlocus([1 1], [1 4 8]) ;
>> rlocfind([1 1], [1 4 8])
Matlab response:
Select a point in the graphics window
selected_point = -3.2261 + 0.0065i
ans = 2.4722
Matlab plot generated:
