nk::wavelet::modwt
Value modwt(const Value &x, int n, const std::string &wname, std::pmr::memory_resource *mr=nullptr)
Maximal-overlap discrete wavelet transform (swc = modwt(x, n, wname)).
nk::wavelet::iswt
Value iswt(const Value &swc, const std::string &wname, std::pmr::memory_resource *mr=nullptr)
Inverse stationary DWT (x = iswt(swc, wname)).
nk::wavelet::imodwt
Value imodwt(const Value &swc, const std::string &wname, std::pmr::memory_resource *mr=nullptr)
Inverse MODWT (x = imodwt(swc, wname)).
nk::wavelet::swt
Value swt(const Value &x, int n, const std::string &wname, std::pmr::memory_resource *mr=nullptr)
Stationary (à trous) discrete wavelet transform (swc = swt(x, n, wname)).
