Function newton 

pub fn newton<T: RealScalar>(
    poly: &Poly<T>,
    epsilon: T,
    max_iter: Option<usize>,
    initial_guess: Option<Complex<T>>,
) -> Result<(Vec<Complex<T>>, u128), Error<Vec<Complex<T>>>>

Find a single root using Newton’s method

Errors

• NoConverge: the root finder did not converge within the given constraints. The best guess so far is returned with the error.\n

Panics

If T is any primitive type, this function does not panic. However, if T does not implement num::FromPrimitive::from_f64 correctly, this function might panic under certain circumstances (casting of extreme values, usually)\n\n
