Function elastic_align_pair_nd 

pub fn elastic_align_pair_nd(
    f1: &FdCurveSet,
    f2: &FdCurveSet,
    argvals: &[f64],
    lambda: f64,
) -> AlignmentResultNd

Align an R^d curve f2 to f1 using the elastic framework.

Finds the optimal warping γ (shared across all dimensions) such that f2∘γ is as close as possible to f1 in the elastic metric.

Arguments

• f1 — Target curves (d dimensions)
• f2 — Curves to align (d dimensions)
• argvals — Evaluation points (length m)
• lambda — Penalty weight (0.0 = no penalty)
