Wavelet Transforms
wave(v)—Returns the wavelet transform of the data in v using the Daubechies four-coefficient wavelet filter.
iwave(u)—Returns the inverse discrete wavelet transform of the data in u.
Wavelet transforms are an alternative to the traditional Fast Fourier Transform.
Arguments
v, u are vectors of length 2m, where m is an integer. Elements of v must be real.
