Requires: MathScript RT Module
b = poly_stable(a)
Stabilizes a polynomial by ensuring that all roots of the polynomial a are located within the unit circle. If a root is located outside of the unit circle, poly_stable uses a circle-based geometric reflection to reflect the root inside of the unit circle.
|a||Specifies a polynomial.|
|b||Returns a stabilized polynomial.|
