grammian (MathScript RT Module Function)
Owning Class: ssanals
Requires: Control Design and Simulation Module and MathScript RT Module
Syntax
Gr = grammian(SysInSS, type)
Legacy Name: gram
Description
Calculates the controllability or observability Grammians of a stable linear time-invariant (LTI) system model in state-space form.
Inputs

|---|---|---|---|---|---|
| SysInSS | Specifies a linear time-invariant (LTI) model in state-space. | ||||
| type | Specifies whether this function computes the controllability or observability Grammians of the SysInSS model. type is a string that can take the following values:

Outputs
| Name | Description |
|---|---|
| Gr | Returns the controllability or observability Grammian of the SysInSS model, depending on the value you specify for the type input. Gr is a real matrix. |
