I tried to use the function 'zpk' (https://www.mathworks.com/help/control/ref/zpk.html) but got the following error:
"Unrecognized function or variable 'zpk'"
I work with Matlab 2020b and tried to run the code from the reference:
zeros = 0;
poles = [1-1i 1+1i 2];
gain = -2;
sys = zpk(zeros,poles,gain)
Am i doing something wrong?

Function "zpk” is implemented in Control System Toolbox. Before moving forward, please check and verify the installation of CST toolbox.
