Excerpt from the Book
6. Numerical Techniques
Due to the lack of closed form solutions, numerical methods are widely used:
- Newton Raphson method
x_(n+1) = x_n - P(x_n) / P'(x_n)
This method converges rapidly when the initial guess is close to a root.
- Durand Kerner method
An iterative technique that approximates all roots simultaneously, including complex ones.
