    pub filters: Vec<FdMatrix>,
    pub scores: FdMatrix,
    pub eigenvalues: Vec<Vec<f64>>,

}

Result of dynamic functional PCA (DPCA).

Produced by dpca (plan 41-01, FTS-03-02). Holds the time-domain dynamic eigen-filters and the dynamic score series.

Divergence from freqdom

Eigenvectors are computed from Re(f̂(θ)) via nalgebra::SymmetricEigen (nalgebra 0.33 has no stable complex Hermitian path without faer); this is exact for the leading dynamic subspace of a Bartlett-windowed estimator. Filters and scores use the Simpson-weighted L2 inner product consistently, so the estimator/score/reconstruction metric matches.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

filters: Vec<FdMatrix>

Dynamic eigen-filters, one per component. filters[c] is a (2L+1) × m FdMatrix: row l_idx holds the filter tap at lag l_idx - L, column j is the grid point.

scores: FdMatrix

Dynamic scores, shape (N - 2L) × ncomp (interior time points only).

eigenvalues: Vec<Vec<f64>>

Per-component eigenvalue trajectory across frequencies: eigenvalues[c] has length n_freqs (negative finite-sample eigenvalues clipped to 0).

n_freqs: usize

Number of Fourier frequencies N.

filter_lag: usize

Filter lag support L (window is [-L, L]).

ncomp: usize

Number of retained dynamic components.

valid_range: (usize, usize)

Inclusive interior time range (L, N-1-L) for which scores are defined.
