Struct CSP 

pub struct CSP { /* private fields */ }

Common Spatial Patterns filter.

Implementations

impl CSP

pub fn new(n_components: usize) -> Self

Create a new CSP with n_components pairs of spatial filters.

The total number of output features will be 2 * n_components.

pub fn fit(&mut self, class1: &[Vec<Vec<f64>>], class2: &[Vec<Vec<f64>>])

Fit CSP filters from two classes of epoch data.

Each epoch is [n_channels][n_samples]. All epochs must have the same number of channels.

pub fn transform(&self, epoch: &[Vec<f64>]) -> Vec<f64>

Transform a single epoch into CSP features.

Returns log(var(W^T X)) for each spatial filter — one value per component. The epoch shape is [n_channels][n_samples].

pub fn transform_all(&self, epochs: &[Vec<Vec<f64>>]) -> Vec<Vec<f64>>

Transform multiple epochs into a feature matrix.

Returns [n_epochs][2*n_components].

pub fn n_features(&self) -> usize

Number of output features (2 × n_components).

pub fn is_fitted(&self) -> bool

Whether the CSP has been fitted.

pub fn eigenvalues(&self) -> &[f64]

Get the eigenvalues.

Trait Implementations

impl Clone for CSP

fn clone(&self) -> CSP

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CSP

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

Formats the value using the given formatter.
