Functions

Rbf2DInterpolator

fun Rbf2DInterpolator(points: List<Vector2>, values: Array<DoubleArray>, smoothing: Double = 0.0, rbf: Rbf, rbfDerivative: Rbf): RbfNDInterpolator<Vector2>

Rbf3DInterpolator

fun Rbf3DInterpolator(points: List<Vector3>, values: Array<DoubleArray>, smoothing: Double = 0.0, rbf: Rbf, rbfDerivative: Rbf): RbfNDInterpolator<Vector3>

Rbf4DInterpolator

fun Rbf4DInterpolator(points: List<Vector4>, values: Array<DoubleArray>, smoothing: Double = 0.0, rbf: Rbf, rbfDerivative: Rbf): RbfNDInterpolator<Vector4>

rbfGaussian

fun rbfGaussian(scale: Double): Rbf

Creates a Gaussian radial basis function (RBF) with the given scale parameter. The resulting RBF computes the exponential decay based on the squared distance scaled by the parameter.

rbfGaussianDerivative

fun rbfGaussianDerivative(scale: Double): Rbf

Generates the derivative of a Gaussian Radial Basis Function (RBF) kernel with respect to the distance. The Gaussian RBF is defined as exp(-scale^2 * distance^2). Its derivative with respect to the distance d is -scale^2 * exp(-scale^2 * d^2).

rbfInverseMultiQuadratic

fun rbfInverseMultiQuadratic(scale: Double): Rbf

Generates a radial basis function (RBF) using the inverse multiquadratic kernel.

rbfInverseMultiQuadraticDerivative

fun rbfInverseMultiQuadraticDerivative(scale: Double): Rbf

rbfInverseQuadratic

fun rbfInverseQuadratic(scale: Double): Rbf

Radial basis function (RBF) using the inverse quadratic formula.

rbfInverseQuadraticDerivative

fun rbfInverseQuadraticDerivative(scale: Double): Rbf

RbfNDInterpolator

fun <T : EuclideanVector<T>> RbfNDInterpolator(points: List<T>, values: Array<DoubleArray>, smoothing: Double = 0.0, rbf: Rbf, rbfDerivative: Rbf): RbfNDInterpolator<T>
