TransferFunctionZeros

TransferFunctionZeros[tfm]

gives a matrix of roots of the numerators in the TransferFunctionModel tfm.

TransferFunctionZeros[tfm,reg]

only gives the roots inside the region reg on the complex plane.

Details

  • A rectangular region reg can be given as {{remin,remax},{immin,immax}}.
  • The default region is the entire complex plane.
