matlab tf get poles
To get the poles of a transfer function in MATLAB, you can use the pole
function. This function returns the poles of the transfer function as a column vector.
Here is an example of how to use the pole
function:
% Define the transfer function
num = [1];
den = [1, 2, 1];
sys = tf(num, den);
% Get the poles
p = pole(sys);
In this example, we define a transfer function with the numerator coefficients [1]
and the denominator coefficients [1, 2, 1]
. We then use the pole
function to get the poles of the transfer function and store them in the variable p
.
