%% MODWPT Details Using Default Wavelet % Obtain the MODWPT of an electrocardiogram (ECG) signal using the default % length 18 Fejer-Korovkin (|'fk18'|) wavelet and the default level, 4. load wecg; wptdetails = modwptdetails(wecg); %% % Demonstrate that summing the MODWPT details over each sample reconstructs % the signal. The largest absolute difference between the original signal % and the reconstruction is on the order of $10^{-11}$, which demonstrates % perfect reconstruction. xrec = sum(wptdetails); max(abs(wecg-xrec'))
