Function WAVELET_1D

Package

Short description

Usage

Input

    x (numeric): The signal to be transformed.
    filters (struct): The filter bank of the wavelet transform.
    options (struct): Various options for the transform:
       options.oversampling (int): The oversampling factor (as a power of 2) 
          with respect to the critical bandwidth when calculating convolu-
          tions (default 1).
       options.psi_mask (boolean): Specifies the wavelet filters in 
          filters.psi for which the transform is to be calculated (default 
          all).
       options.x_resolution (int): The resolution of the input signal x as
          a power of 2, representing the downsampling of the signal with
          respect to the finest resolution (default 0).

Output

    x_phi (numeric): x filtered by the lowpass filter filters.phi.
    x_psi (cell): cell array of x filtered by the wavelets filters.psi.
    meta_phi, meta_psi (struct): meta information on x_phi and x_psi, respec-
       tively.
