zero (MathScript RT Module Function)
Owning Class: dynchar
Requires: Control Design and Simulation Module and MathScript RT Module
Syntax
[z, K] = zero(SysIn)
Description
Calculates the zeros and gain of a system model.
Inputs
| Name | Description |
|---|---|
| SysIn | Specifies a linear time-invariant (LTI) model in transfer function, zero-pole-gain, or state-space form. |
Outputs
| Name | Description |
|---|---|
| z | Returns the zeros of the SysIn model. z is a complex vector. For multiple-input multiple-output (MIMO) system models, this function converts transfer function and zero-pole-gain models to state-space form. This function then calculates the transmission zeros of the state-space model. These poles are not necessarily identical to the poles you can obtain by using the Smith-McMillan form. |
| K | Returns the steady-state gain matrix of the SysIn model. K is a complex vector. |
Details
The following table lists the support characteristics of this function.

| Supported on RT targets | Yes |
| Suitable for bounded execution times on RT | Not characterized |
Examples
SysIn = zpk([1], [1, 2, 1], 2)
z = zero(SysIn)
