Function au::complex::damp

pub fn damp<T: Float>(c: Complex<T>) -> T

Calculate the damping of a complex number, it corresponds to the cosine of the angle between the segment joining the complex number to the origin and the real negative semiaxis.

By definition the damping of 0+0i is -1.

Arguments

• c - Complex number

Example

use au::{num_complex::Complex, damp};
let i = Complex::new(0., 1.);
assert_eq!(0., damp(i));
