Struct PeriodicBSplineBasisSpec 

pub struct PeriodicBSplineBasisSpec {
    pub degree: usize,
    pub num_basis: usize,
    pub period: f64,
    pub origin: f64,
    pub penalty_order: usize,
}

Configuration for a dense one-dimensional periodic B-spline basis.

The basis lives on a circle parameterized by origin + [0, period). It is vector-valued agnostic: the same scalar periodic design can be shared by any number of ambient output coordinates, so a single fitted curve u -> R^d_ambient can trace ellipses, ovals, and skewed/distorted closed loops without assuming a unit circle embedding.

Fields

degree: usize

Polynomial degree of the cardinal B-spline pieces.

num_basis: usize

Number of periodic basis functions around the circle.

period: f64

Period of the parameter coordinate.

origin: f64

Parameter value identified with zero phase.

penalty_order: usize

Cyclic finite-difference order used by curve fitting penalties.

Implementations

impl PeriodicBSplineBasisSpec

pub fn new( degree: usize, num_basis: usize, period: f64, origin: f64, penalty_order: usize, ) -> Self

Construct a validated-looking spec. Full semantic validation is still performed by builders so deserialized specs receive identical checks.
