LinearSystems Namespace

void TransferFunToZeroPole(TVec *z, TVec *p, double &k, TVec *Num, TVec *Den);

Remarks:

Convert a transfer function defined with numerator Num and denominator Den in to its zero-pole form with zeros Z, poles P and gain K. The routine calls PolyRoots routine from the Polynoms unit. Numerator and denominator can be real or complex.

A rational polynomial can be converted to zero pole form by finding the roots of the numerator and denominator: (x^2 - 7x + 12)/(x^2 - 3x + 2) Zero pole form:
((x-3)(x-4))/((y-2)(y-1))
