This is generally used in the context of generic programming. Using the .angle() method instead is more common. Returns None if the angle is zero.

pub fn from_cos_sin_unchecked(cos: N, sin: N) -> Self

let rot = UnitComplex::from_cos_sin_unchecked(angle.cos(), angle.sin());

assert_relative_eq!(rot * Point2::new(3.0, 4.0), Point2::new(-4.0, 3.0));

) -> Self

pub fn from_matrix(m: &Matrix2<N>) -> Self

Builds an unit complex by extracting the rotation part of the given transformation m.

This is an iterative method. See .from_matrix_eps to provide mover convergence parameters and starting solution. This implements “A Robust Method to Extract the Rotational Part of Deformations” by Müller et al.

    m: &Matrix2<N>,
    eps: N,
    max_iter: usize,
