LinearSystems.LTIZeros Method

procedure LTIZeros(const z: TVec; out gain: Double; const A: TMtx; const B: TVec; const C: TVec; const D: Double);

Find zeros of a linear time invariant system in state-space form.

#	Name	Type
1	z	TVec
2	gain	Double
3	A	TMtx
4	B	TVec
5	C	TVec
6	D	Double

Result: stored in self (calling object)

Remarks:

Compute zeros of a linear time invariant system represented in state space form. The resulting zeros are placed in Z and computed system gain in Gain.
