is_stable (MathScript RT Module Function)
Owning Class: info
Requires: Control Design and Simulation Module and MathScript RT Module
Syntax
stable = is_stable(SysIn)
stable = is_stable(SysIn, tol)
Legacy Name: isstable
Description
Determines whether a system model is stable.
Inputs
| Name | Description |
|---|---|
| SysIn | Specifies a linear time-invariant (LTI) model in transfer function, zero-pole-gain, or state-space form. |
| tol | Specifies the tolerance. The default value of tol is 0.00000001. tol is a real scalar. |
Outputs
| Name | Description |
|---|---|
| stable | Returns 1 if the SysIn model is stable. This function returns 0 if the SysIn model is not stable. stable is a Boolean. |
Details

| Suitable for bounded execution times on RT | Not characterized |
Examples
SysIn = ss(1, 1, 2, 0);
stable = is_stable(SysIn);
