Struct Coiflet 

pub struct Coiflet { /* private fields */ }

Coiflet wavelet family

Coiflets are a family of wavelets designed by Ingrid Daubechies at the request of Ronald Coifman. The wavelet function has 2N vanishing moments and the scaling function has 2N-1 vanishing moments. They are more symmetrical than Daubechies wavelets.

Implementations

impl Coiflet

pub fn new(order: usize) -> Self

Create a Coiflet wavelet of given order Order represents the Coiflet order. Supported orders are 1 through 5.

pub fn coif1() -> Self

pub fn coif2() -> Self

pub fn coif3() -> Self

pub fn coif4() -> Self

pub fn coif5() -> Self
