Struct FunctionalData 

pub struct FunctionalData {
    pub grid: Vec<f64>,
    pub observations: Vec<Vec<f64>>,
}

Functional data: a collection of curves observed on a common grid.

Each observation is a function sampled at the same grid points. For example, temperature curves measured hourly over multiple days, or growth curves of different subjects measured at the same ages.

Fields

grid: Vec<f64>

Common evaluation grid (sorted, length T)

observations: Vec<Vec<f64>>

Observed curves: observations[i] is the i-th curve, each of length T

Implementations

impl FunctionalData

pub fn new(grid: Vec<f64>, observations: Vec<Vec<f64>>) -> StatsResult<Self>

Create new functional data, validating dimensions.

Errors

Returns an error if:

• grid is empty
• observations is empty
• Any observation has a different length than grid

pub fn n_curves(&self) -> usize

Number of curves (observations).

pub fn n_grid(&self) -> usize

Number of grid points.

Trait Implementations

impl Clone for FunctionalData

fn clone(&self) -> FunctionalData

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FunctionalData

fn fmt(&self, f: &mut Formatter<'_>) -> Result
