IWT_PO

PURPOSE

IWT_PO -- Inverse Wavelet Transform (periodized, orthogonal)

SYNOPSIS

function x = IWT_PO(wc,L,qmf)

DESCRIPTION

 IWT_PO -- Inverse Wavelet Transform (periodized, orthogonal)
  Usage
    x = IWT_PO(wc,L,qmf)
  Inputs
    wc     1-d wavelet transform: length(wc) = 2^J.
    L      Coarsest scale (2^(-L) = scale of V_0); L << J;
    qmf    quadrature mirror filter
  Outputs
    x      1-d signal reconstructed from wc

  Description
    Suppose wc = FWT_PO(x,L,qmf) where qmf is an orthonormal quad. mirror
    filter, e.g. one made by MakeONFilter. Then x can be reconstructed by
      x = IWT_PO(wc,L,qmf)
