nk::wavelet::dyaddown
Value dyaddown(const Value &x, int odd=0, char type='c', std::pmr::memory_resource *mr=nullptr)
Dyadic downsampling — y = dyaddown(x, odd, type).
nk::wavelet::dyadup
Value dyadup(const Value &x, int odd=1, char type='c', std::pmr::memory_resource *mr=nullptr)
Dyadic upsampling with zero insertion — y = dyadup(x, odd, type).
nk::wavelet::wmaxlev
Value wmaxlev(const Value &N, const std::string &wname, std::pmr::memory_resource *mr=nullptr)
Maximum wavelet decomposition level — L = wmaxlev(N, wname).
