Struct IsplineFunctionPenalties 

Source 
pub struct IsplineFunctionPenalties {
    pub roughness: Array2<f64>,
    pub roughness_nullspace_dim: usize,
    pub nullspace_shrinkage: Option<Array2<f64>>,
}
Expand description

Exact function-space penalties for the anchored I-spline basis.

roughness is the derivative Gram of the represented value function and nullspace_shrinkage, when requested and structurally non-empty, is the exact L² metric restricted to null(roughness). The latter is a separate REML coordinate; it never adds a coefficient-space ridge to directions the primary roughness already controls.
