PyWavelets is a Python wavelet transforms module that includes:

    * nD Forward and Inverse Discrete Wavelet Transform (DWT and IDWT)
    * 1D and 2D Forward and Inverse Stationary Wavelet Transform (Undecimated Wavelet Transform)
    * 1D and 2D Wavelet Packet decomposition and reconstruction
    * 1D Continuous Wavelet Tranfsorm
    * Computing Approximations of wavelet and scaling functions
    * Over 100 built-in wavelet filters and support for custom wavelets
    * Single and double precision calculations
    * Real and complex calculations
    * Results compatible with Matlab Wavelet Toolbox (TM)
