yields a disjunction of equations which represent numerical approximations to the roots of a polynomial equation.
- NRoots gives several identical equations when roots with multiplicity greater than one occur.
- NRoots has the following options:
MaxIterations Automatic maximum number of iterations to use Method Automatic method to use PrecisionGoal Automatic the precision sought StepMonitor None expression to evaluate at each step
- Possible settings for the Method option include: "Aberth", "CompanionMatrix", and "JenkinsTraub".
