Struct Daubechies 

pub struct Daubechies { /* private fields */ }

Daubechies wavelets - a family of orthogonal wavelets

Daubechies wavelets are a family of orthogonal wavelets with compact support. They are characterized by a maximal number of vanishing moments for a given support width. This implementation includes db2 and db4.
