Matlab Code For Wavelet Transform Signal Decomposition

Webwavedec2 does not enforce a maximum level restriction. Use wmaxlev to determine the maximum decomposition level possible of the matrix X using the wavelet wname . The maximum level is the last level for which at least one coefficient is correct. Webwavedec2is a two-dimensional wavelet analysis function. [C,S] = wavedec2(X,N,'wname')returns the wavelet decomposition of the matrix Xat level N, using the wavelet named in string 'wname' (see wfiltersfor more information). Outputs are the decomposition vector Cand the corresponding bookkeeping matrix S.
