Struct WaveletPacketNode 

pub struct WaveletPacketNode {
    pub coeffs: Vec<f64>,
    pub level: usize,
    pub index: usize,
}

A single node in the wavelet packet tree.

The node stores the subband coefficients and its position in the tree. Position is identified by (level, index) where index ∈ [0, 2^level).

Fields

coeffs: Vec<f64>

Subband coefficients at this node.

level: usize

Decomposition level (0 = root, i.e. the original signal).

index: usize

Node index within the level (frequency-ordered).

Implementations

impl WaveletPacketNode

pub fn new(coeffs: Vec<f64>, level: usize, index: usize) -> Self

Create a new node.

pub fn is_root(&self) -> bool

Returns true if this node is the root (level 0).

Trait Implementations

impl Clone for WaveletPacketNode

fn clone(&self) -> WaveletPacketNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WaveletPacketNode

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

Formats the value using the given formatter.
