Struct GraphBandpass 

pub struct GraphBandpass {
    pub low_k: usize,
    pub high_k: usize,
}

Ideal band-pass spectral graph filter.

Retains only frequency components whose indices fall in [low_k, high_k), i.e. the band between the low_k-th and high_k-th eigenvalue.

Fields

low_k: usize

Inclusive lower index of the retained frequency band.

high_k: usize

Exclusive upper index of the retained frequency band.

Implementations

impl GraphBandpass

pub fn new(low_k: usize, high_k: usize) -> Self

Create a new band-pass filter for the frequency band [low_k, high_k).

impl GraphFilter for GraphBandpass

fn frequency_response(&self, gft: &GraphFourierTransform) -> Array1<f64>

Return the frequency response h(λ) for each eigenvalue in gft.

fn apply( &self, gft: &GraphFourierTransform, signal: &Array1<f64>, ) -> Result<Array1<f64>>
