create a transfer function in matlab

The transfer function in MATLAB can be created using the tf command followed by the numerator and denominator polynomial coefficients. Here's an example:

main.m
% define numerator and denominator polynomial coefficients
num = [1 2];
den = [1 3 2];

% create transfer function using tf command
tf_sys = tf(num,den);

% display transfer function
disp(tf_sys);
197 chars
10 lines

This will create a transfer function with numerator s^1 + 2 and denominator s^2 + 3s + 2. The tf function takes the ratio of the two polynomials to create the transfer function.

You can use transfer functions in control systems engineering to analyze the behavior of a system, design controllers, and simulate system behavior.
