Wavelet packet transforms

wpt(a,b,f,[o,[i]]) Returns the wavelet packet transform of the array a with respect to basis or level b by the wavelet filter f. f can have an offset o and negation i .

iwpt(w,b,f,[o,[i]]) Returns the inverse wavelet packet transform of the array w with respect to basis b by the wavelet filter f. f can have an offset o and negation i .
