%% 3-D Wavelet Transform % Find the 3-D DWT of a volume. Construct 8-by-8-by-8 matrix of integers % 1 to 64 and make the data 3-D. M = magic(8); X = repmat(M,[1 1 8]); %% % Obtain the 3-D discrete wavelet transform at level 1 using the Haar % wavelet and the default whole-point symmetric extension mode. wd1 = wavedec3(X,1,'db1');
