Struct FittedAtomCarveInput 

pub struct FittedAtomCarveInput {
    pub phi_a: Array2<f64>,
    pub phi_b: Array2<f64>,
    pub surface: TensorSurfaceFit,
    pub joint_covariance: Array2<f64>,
}

The real-fit producer of a representational CarveInput from a fitted d = 2 product atom (#993).

Holds the two factor bases the carve consumes plus the TensorSurfaceFit re-fit of the atom’s own ambient reconstruction. The fit is what supplies the scale-included decoder-coefficient covariance (coeff_covariance / joint_covariance) — the production inner Hessian is a DIFFERENT parameterization (tangent frames, not tensor coefficients) and cannot offer the carve a coefficient-space Vb, so the carve’s covariance is re-derived here on the same empirical code measure the test centers against (the coherence the module docs require). Owns its arrays so the borrowed CarveInput built via Self::representational_carve_input can reference them for the lifetime of the carve call.

Fields

phi_a: Array2<f64>

Factor-A basis on the code sample, n × M₁.

phi_b: Array2<f64>

Factor-B basis on the code sample, n × M₂.

surface: TensorSurfaceFit

REML re-fit of the atom’s ambient reconstruction onto the tensor basis, carrying the per-channel coefficient matrices and their scale-included covariance.

joint_covariance: Array2<f64>

Cross-dimension joint covariance of the stacked coefficient vector (TensorSurfaceFit::joint_covariance), materialized once so the borrowed CarveInput can reference it.

Implementations

impl FittedAtomCarveInput

pub fn representational_carve_input(&self) -> CarveInput<'_>

Borrow this bundle as a representational CarveInput ready for carve. The coefficient covariance and the joint covariance come from the REML re-fit; the gauge kernels default to the partition-of-unity convention (u = 1), which is the correct centered- basis null direction for the constant-leading harmonic factor bases.
