This video demonstrates how to obtain root locus of a given transfer function using MATLAB.
--------------------------------------------------
MATLAB program for Root Locus

clc;
clear all;

num = [1 2]; % Enter the coefficients of numerator
den = [1 2 2]; % Enter the coefficients of denominator

sys = tf(num,den) % computes transfer function

rlocus(sys)

-----------------------------------------------------------

syms s;
num = [1]; % Enter the coefficients of numerator
den = sym2poly(s*(s+1)*(s+2)*(s+3)); % Enter the coefficients of denominator

sys = tf(num, den) % Obtain the transfer function

rlocus(sys)
