LinearSystems.LTIZeros Method

void LTIZeros(TVec z, ref Double gain, TMtx A, TVec B, TVec C, Double D)

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

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.
