Trait for centrosymmetric kernels

Centrosymmetric kernels satisfy K(x, y) = K(-x, -y) and can be decomposed into even and odd components for efficient computation.

Required Methods§

Source

fn compute_reduced<T: CustomNumeric + Copy + Debug>( &self, x: T, y: T, symmetry: SymmetryType, ) -> T

Compute the reduced kernel value

K_red(x, y) = K(x, y) + sign * K(x, -y) where sign = 1 for even symmetry and sign = -1 for odd symmetry

Source

fn lambda(&self) -> f64

Get the cutoff parameter Λ (lambda)

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
