Maximum wavelet decomposition level



wmaxlev is a one- or two-dimensional wavelet or wavelet packets oriented function.

wmaxlev can help you avoid unreasonable maximum level values. L = wmaxlev(S,'wname') returns the maximum level decomposition of signal or image of size S using the wavelet named in the string 'wname' (see wfilters for more information).

wmaxlev gives the maximum allowed level decomposition, but in general, a smaller value is taken.

Usual values are 5 for the one-dimensional case, and 3 for the two-dimensional case.
