TransferFunctionPoles

TransferFunctionPoles[tfm]
gives a matrix of roots of the denominators in the TransferFunctionModel tfm.

TransferFunctionPoles[tfm,reg]
only gives the roots inside the region reg on the complex plane.

DetailsDetails

  • A rectangular region reg can be given as .
  • The default region is the entire complex plane.
