%% Check Passivity of Object % Create a scalar rational function object and check the passivity of the % object.

TF = s2tf(ckt.AnalyzedResult.S_Parameters); TF_Object = rationalfit(ckt.AnalyzedResult.Freq, TF); %% % Check the passivity of the rational function object. Is_Passive = ispassive(TF_Object)
