Fields§

§penalty_index: usize§penalty_indices: Vec<usize>§global_range: Range<usize>§total_p: usize§x_psi_local: Array2<f64>§s_psi_components_local: Vec<Array2<f64>>§x_psi_psi_local: Array2<f64>§s_psi_psi_components_local: Vec<Array2<f64>>§aniso_group_id: Option<usize>§aniso_cross_designs: Option<Vec<(usize, Array2<f64>)>>

Pre-computed cross-derivative design matrices for other axes in the same aniso group: Vec of (axis_offset_in_group, matrix).

§aniso_cross_penalty_provider: Option<Arc<dyn Fn(usize) -> Result<Vec<Array2<f64>>, EstimationError> + Send + Sync + 'static>>

On-demand cross-penalty second derivatives ∂²S_m/∂ψ_a∂ψ_b for axes in the same anisotropy group. The input is the other axis offset in the group, and the output is one local penalty matrix per active penalty.

§implicit_operator: Option<Arc<ImplicitDesignPsiDerivative>>

Optional implicit design-derivative operator (shared across all axes in the same aniso group). When present, x_psi_local and x_psi_psi_local may be zero-sized, and design-derivative matvecs should go through this operator using implicit_axis as the axis index.

§implicit_axis: usize

Which axis in the implicit operator this entry corresponds to.
