Struct RadialBasisFunction 

Source 
pub struct RadialBasisFunction {
    pub kind: RbfKind,
    pub shape: f64,
    pub centers: Vec<Vec<f64>>,
    pub coeffs: Vec<f64>,
}
Expand description

Radial basis function interpolation in arbitrary dimension.

Fields§

§kind: RbfKind

RBF kernel type.

§shape: f64

Shape parameter c or σ.

§centers: Vec<Vec<f64>>

Data points (each row is one point).

§coeffs: Vec<f64>

Fitted coefficients.

Implementations§

Source§

impl RadialBasisFunction

Source

pub fn fit( kind: RbfKind, shape: f64, points: &[Vec<f64>], values: &[f64], ) -> Self

Create an RBF interpolant fitted to data.

points: N×D matrix of data locations. values: N values at those locations.

Source

pub fn eval(&self, x: &[f64]) -> f64

Evaluate interpolant at a new point x.
