Struct EWTConfig 

#[non_exhaustive]
pub struct EWTConfig {
    pub max_bands: usize,
    pub boundary_detection: BoundaryDetection,
    pub spectrum_preproc: SpectrumPreproc,
    pub gamma_strategy: GammaStrategy,
    pub log_spectrum: bool,
}

Configuration for ewt.

Builder-style setters mirror super::ceemdan::CEEMDAN; the struct is #[non_exhaustive] so downstream callers must construct via EWTConfig::default (or one of the preset constructors) and chain with_* methods.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

max_bands: usize

Hard upper bound on the number of detected boundaries N. The returned EWTResult::components has length N + 1 (one scaling band plus N wavelet bands). Default 8.

boundary_detection: BoundaryDetection

Boundary-detection strategy. Default BoundaryDetection::LocalMaxMinima with min_peak_separation = π / 16.

spectrum_preproc: SpectrumPreproc

Spectrum preprocessing applied before peak detection. Default SpectrumPreproc::None.

gamma_strategy: GammaStrategy

Transition-width strategy. Default GammaStrategy::Auto.

log_spectrum: bool

Use ln(1 + |X(ω)|) instead of |X(ω)| for peak detection. The log-spectrum compresses dynamic range so weaker harmonics survive alongside dominant tones. Default true.

Implementations

impl EWTConfig

pub fn with_max_bands(self, max_bands: usize) -> Self
