stabilizable = TransferFunction.Analysis.isStabilizable(tf, method)
Function TransferFunction.Analysis.isStabilizable checks the Stabilizability of a transfer function. Therefore, the transfer function is converted into a state space representation which is applied to StateSpace.Analysis.isStabilizable. The transfer function is stabilizable if all unstable poles are controllable.
