Why this code give me Zero out put

%fundamental frequency f1 f1=60;

% fundamental angular frequency omegaone omegaone =2.*pi.*f1;

%frequency range f f=[0.1: 0.1: 10000];

%angular frequency omegadot omegadot=2.*pi.*f;

%variable s s=j.*omegadot;

%RSC Integral Gain Kri Kri=0.027;

%RSC Proportional Gain

Krp=0.052

%Current Compensator function RSC current controller Hr

Hr= Krp+(Kri./(s-j.*omegaone));
