MATLAB: Creat a loop to generate a a mean value of data which I got form TXT files then plot the results

for loopstructtext file

 I trying to do script to evalute my lab data into matlab, I have lots of txt files for many samples, each sample has 30 txt files. I did a function to get the data from these files and store them into a structure that contains data and labels. I would like to know if it is possible to load all the 30 files using loop instead of line by line .
function s = try1(fn) % adapt for other file format according to your needs fid = fopen(fn); s.data = []; % skip first lines
    for k=1:6
        l = fgetl(fid);
        % read header
        a = regexp(l,',','split');
        s.labels = a;
        l = fgetl(fid);
        k=0;
    end
    while( (l~=-1)&(k<130) )
        l = l(1:end-1);
        a = regexp(l,', ','split');
        a = regexpre
        p(a, ',','.');
        s.data = [s.data; str2double(a(2:4))];
        l = fgetl(fid);
        k = k+1;
    end
    fclose(fid);
end
then i used this code to fetch the data form folder directory
     dataDirectory = 'c:/myDirectory';
     allFilesDir = dir(fullfile(dataDirectory , '*.txt'));
     allFN = {allFilesDir.name}
     % Or do this:
      % allFN = {'file1.txt', 'file2.txt'};
     result = [];
      for ind = 1:length(allFN)
      myFN = fullfile(dataDirectory, allFN{ind});
       result(ind) = try1(myFN);
      end
      % Now get the mean:
      myMean = mean([result.data])
but i got this error The following error occurred converting from struct to double: Error using ==> double Conversion to double from struct is not possible. Error in ==> getmean at 13 result(ind) = try1(myFN); any idea about porb \\

Best Answer

I went to 3D array option then squeeze my results to get the results in this way
            result(:,:,n)
            G=(squeeze(myMean));
But I got them into 3*35 not 35*3 I will try to find a way to flip the data as I want ..
