Struct PeriodicSplineCurve 

pub struct PeriodicSplineCurve {
    pub spec: PeriodicBSplineBasisSpec,
    pub coefficients: Array2<f64>,
}

Fitted vector-valued periodic spline curve.

coefficients has shape (num_basis, ambient_dim). Evaluation multiplies the periodic scalar basis row by every output column, preserving any anisotropic stretching, skew, or non-circular shape present in the training coordinates.

Fields

spec: PeriodicBSplineBasisSpec

coefficients: Array2<f64>

Implementations

impl PeriodicSplineCurve

pub fn ambient_dim(&self) -> usize

Number of coordinates in the ambient output space.

pub fn evaluate( &self, u: ArrayView1<'_, f64>, ) -> Result<Array2<f64>, BasisError>

Evaluate the fitted curve at arbitrary parameter values. Values outside the base interval are wrapped modulo period.

pub fn evaluate_derivative( &self, u: ArrayView1<'_, f64>, ) -> Result<Array2<f64>, BasisError>

Evaluate the derivative of the fitted curve with respect to its scalar periodic parameter.
