Zeros and gain of SISO dynamic system
z = zero(sys)
[z,gain] = zero(sys)
[z,gain] = zero(sysarr,J1,...,JN)
SISO dynamic system model.
Array of dynamic system models.
Indices identifying the model
Column vector containing the locations of zeros in
Calculate the zero locations and overall gain of the transfer function
H = tf([4.2,0.25,-0.004],[1,9.6,17]); [z,gain] = zero(H)
z = -0.0726 0.0131 gain = 4.2000
The zero locations are expressed in radians per second, because
the time unit of the transfer function (
is seconds. Change the model time units, and
pole locations relative to the new unit.
H = chgTimeUnit(H,'minutes'); [z,gain] = zero(H)
z = -4.3581 0.7867 gain = 4.2000
To calculate the transmission zeros of a multi-input, multi-output
