Purpose Transmission zeros of LTI models
Syntax z = zero(sys)
[z,gain] = zero(sys)
Description zero computes the zeros of SISO systems and the transmission zerosof MIMO
systems. For a MIMO system with matrices , the transmission
zeros are the complex values for which the normal rank of
drops.
z = zero(sys) returns the (transmission) zeros of the LTI model sys as a
column vector.
[z,gain] = zero(sys) also returns the gain (in the zero-pole-gain sense) if
sys is a SISO system.
Algorithm The transmission zeros are computed using the algorithm in [1].
See Also pole Compute the poles of an LTI model
pzmap Compute the pole-zero map
