WebNow, assuming that you want to modify one of those mentioned coefficients, you need to be familiar with the usage of wavedec2. This function puts all coefficients one after the other in one row. Here is my post about working with MATLAB's wavelet toolbox. "Example 5" demonstrates how wavedec2 stores coefficients. WebDescription. x = waverec2 (c,s,wname) performs a multilevel wavelet reconstruction of the matrix x based on the wavelet decomposition structure [ c, s] and the wavelet specified by wname. See wavedec2. x = waverec2 (c,s,wname) is equivalent to x = appcoef2 (c,s,wname,0). x = waverec2 (c,s,LoR,HiR) reconstructs x using the specified lowpass …
