Together with using the -append flag when you save()

Make sure you use a different variable name each time you save, or else the new value will overwrite the old value.

MATLAB: What is wrong with the code

I'd store the results into a cell array or regular array and then just write out the array with one call to save() after the loop exits.

for k = 1 : n
  % Code to read in imgarray, then...
   fea{k} = waveletfea(imgarray);
end
folder = pwd;
baseFileName = 'feature.mat';
fullFileName = fullfile(folder, baseFileName);
save(fullFileName,'fea');

but first you have to make sure you have write access to the folder.
