rfftwt

Weight the real Fourier series <code>xrfft</code> of even length by a weight
sequence <code>wt</code>. The first term of <code>xrfft</code> is left alone, and the
weights are then applied to pairs of terms in <code>xrfft</code>. Note:
<code>wt</code> is half the length of <code>xrfft</code>.

math

Performs 1, 2 and 3D real and complex-valued wavelet transforms,
nondecimated transforms, wavelet packet transforms, nondecimated
wavelet packet transforms, multiple wavelet transforms,
complex-valued wavelet transforms, wavelet shrinkage for
various kinds of data, locally stationary wavelet time series,
nonstationary multiscale transfer function modeling, density
estimation.
