Struct GraphFilter 

pub struct GraphFilter { /* private fields */ }

Graph filter that applies spectral operations

Implementations

impl GraphFilter

pub fn new(laplacian: ScaledLaplacian, filter: SpectralFilter) -> Self

Create graph filter from adjacency and filter specification

pub fn from_adjacency(adj: &[f64], n: usize, filter: SpectralFilter) -> Self

Create from dense adjacency matrix

pub fn from_sparse( edges: &[(usize, usize, f64)], n: usize, filter: SpectralFilter, ) -> Self

Create from sparse edges

pub fn apply(&self, signal: &[f64]) -> Vec<f64>

Apply filter to signal: y = h(L) * x Uses Chebyshev recurrence: O(K*m) where K is degree, m is edges

pub fn apply_n(&self, signal: &[f64], n_times: usize) -> Vec<f64>

Apply filter multiple times (for stronger effect)

pub fn energy(&self, signal: &[f64]) -> f64

Compute filter energy: x^T h(L) x

pub fn lambda_max(&self) -> f64

Get estimated spectral range
