% BTW: If you access the data by loop iteration, eg dataStore(k,:) you might want to consider transposing your dataStore.

%

filenameC = getFileNames();

nFile = length(filenameC);

nData = 200;

dataStore = zeros([nData,nFile]); % preallocate for speed

%

for kFile = 1:nFile

dataStore(kFile,:) = myFunctionInvolvingFilename(filenameC{kFile}); # MUST return 800-long data, never empty

end

% Enjoy :)
