for i = 1:60;
x = y(i,:) ;
F = wden(x,'rigrsure','s','mln',5,'db5');
end
%It only save the last filterd signal in the variable (F) and I need it to save all of the filterd signals.

F data can be store in cell array.
F=cell(1,60);
for i = 1:60;
x = y(i,:) ;
F{i}= wden(x,'rigrsure','s','mln',5,'db5');
end

% I want to do feature extraction for signals and then apply ANN classification on them,, can you help please?
Fs = 50; sf = waveletScattering('SignalLength', 4950, 'SamplingFrequency', Fs) ;
s = cell(120,1); parfor j = 1:120; r = featureMatrix(sf, f(j, :)) ; s{j, 1} = r; end
h = cell2mat(s) ; b = cell2table(s) ; c = table2dataset(b);
%the single signal was in one row, but after this it becomes 202rows×10columns, and I can't apply ANN like this Any ideas?
