Trait Kernel 

pub trait Kernel: Send + Sync {
    // Required method
    fn eval(&self, a: &[f64], b: &[f64]) -> f64;

    // Provided method
    fn name(&self) -> &str { ... }
}

Object-safe kernel function for KRLS and other kernel methods.

A kernel computes an inner product in a (possibly infinite-dimensional) feature space without explicitly computing the feature map.

Required Methods

fn eval(&self, a: &[f64], b: &[f64]) -> f64

Evaluate the kernel function k(a, b).

Provided Methods

fn name(&self) -> &str

Human-readable kernel name (for Debug output).
