Dear all I am using the matlab-wavelet toolbox ver 1.2 and the follwoing function wdencmp is giving error for the innvalid argument list. although the example I am running is a matlab example but still it is giving error. The code for the example is as follows and you will find it at page no 2-20 of wavelet user guide your help in this regard will be deeply appreciated %loading the signal load leleccum; %setting the variables s= leleccum(1:3920); ls = length(s); %performing a multi level Wav Decomposition [C,L] = wavedec(s,3,'db1'); [thr,sorh,keepapp] = ddencmp('den','wv',s) W = 'db1' N=3 clean = wdencmp('gb1',C,L,W,N,thr,sorh,keepapp) figure subplot(2,1,1) ; plot(s(2000:3920)); title('Oriinal'); axis off subplot(2,1,2) ; plot(clean(2000:3920)); title('De-noised'),axis off |
