Struct AberthStep

Source

pub struct AberthStep<'a> {
    pub coeffs: &'a [f64],
    pub coeffs1: &'a [f64],
}

Expand description

One Aberth-Ehrlich correction for a single root.

This mirrors ginger::detail::aberth_step in ginger-cpp.

Fields§

§coeffs: &'a [f64]

Polynomial coefficients (highest degree first).

§coeffs1: &'a [f64]

Derivative coefficients of coeffs.
