WebDescription. [C,S] = wavedec2 (X,N,wname) returns the wavelet decomposition of the matrix X at level N using the wavelet wname. The output decomposition structure consists of the wavelet decomposition vector C and the bookkeeping matrix S, which contains the number of coefficients by level and orientation. Webwavedec performs a multilevel one-dimensional wavelet analysis using either a specific wavelet ('wname') or a specific wavelet decomposition filters (Lo_D and Hi_D, see wfilters). [C,L] = wavedec(X,N, ' wname ' ) …
