TransferFunctionModel
TransferFunctionModel[g[s],s] represents the model of the transfer-function matrix g[s] with complex variable s.
TransferFunctionModel[{n[s],d[s]},s] specifies the numerator n[s] and denominator d[s] of a transfer-function model.
TransferFunctionModel[{z,p,g},s] specifies the zeros z, poles p, and gain g of a transfer-function model.
TransferFunctionModel[sys] gives the transfer-function model of the systems model sys.
