Struct PrincipalDirections 

#[non_exhaustive]
pub struct PrincipalDirections {
    pub pc_index: usize,
    pub c_values: Vec<f64>,
    pub amplitude_curves: FdMatrix,
    pub phase_curves: FdMatrix,
}

Principal-direction curves at μ ± c·σⱼ for a chosen jfPCA component (VEE-04).

Created by JfpcaModel::principal_directions. Each row i of amplitude_curves / phase_curves corresponds to c_values[i].

At c = 0 the amplitude curve reproduces JfpcaModel::karcher_mean within 1e-10 (the make-or-break gate).

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.

pc_index: usize

PC index (0-based).

c_values: Vec<f64>

c multipliers supplied by the caller (length n_c).

amplitude_curves: FdMatrix

Amplitude (function-space) curves at each c value (n_c × m).

phase_curves: FdMatrix

Phase (warping-function) curves at each c value (n_c × m).
