%% Peak Gain with Specified Accuracy % Compute the peak gain of the resonance in the transfer function with a % relative accuracy of 0.01%. %% % % $$sys = {{90} \over {{s^2} + 1.5s + 90}}.$$ % %% sys = tf(90,[1,1.5,90]); gpeak = getPeakGain(sys,0.0001) %% % The second argument specifies a relative accuracy of 0.0001. The |getPeakGain| % command returns a value that is within 0.0001 (0.01%) of the true peak gain of % the transfer function. By default, the relative accuracy is 0.01 (1%).
