1 Introduction to MATLAB's pole command
The pole command is a simple one. There is only 1 usage of it:
>> p = pole(sys);
This will return the poles of the LTI model sys. It doesn't matter if sys is a State Space object, Transfer Function, Zero-Pole-Gain model, or FRD (typically used fo rmeasured data).
- This function requires the Control System Toolbox.
The function will not necessarily compute multiple poles accurately. In other words if you have 2 or more poles at the poles may appear as a circular cluster of poles centered at with a radius on the order of
- is the machine precision (eps) and
- is the number of poles at .
