Function align_to_target 

pub fn align_to_target(
    data: &FdMatrix,
    target: &[f64],
    argvals: &[f64],
) -> AlignmentSetResult

Align all curves in data to a single target curve.

Arguments

• data — Functional data matrix (n × m)
• target — Target curve to align to (length m)
• argvals — Evaluation points (length m)

Returns

AlignmentSetResult with all warping functions, aligned curves, and distances.
