Evaluate natural frequency bound on linear system
c = evalRequirement(req,lin_sys)
Requirement object (sdo.requirements.StepResponseEnvelope, ...).
For MIMO systems, the bound applies to each input/output (I/O) channel.
Linear system (tf, ss, zpk, frd, genss, or genfrd).
Evaluate natural frequency requirement.
req = sdo.requirements.PZNaturalFrequency; sys = tf(0.5,[1 3 3 1]); c = evalRequirement(req,sys);
c is positive, which indicates that the system does not satisfy the natural frequency requirement.
