MATLAB: Read mulitple files in matlab

while loop

This is my code. I want to find a way to (maybe a for loop or something) that make the fopen read multiple files ending on data.txt. I have 1_data.txt, 2_data.txt ect. in a folder on my computer.
data = fopen('1data.txt', 'r');
     x = fgetl(fid);
     ii = 0;
        while ischar(x)
           ii = ii + 1;
           tmp = textscan(tline, '%s', 'delimiter', ' ', 'MultipleDelimsAsOne', 1);
           tmp = tmp{1};
           t(ii) = str2num(tmp{8});
           g(ii) = str2num(tmp{9});
          x = fgetl(fid);
        end 
fclose(fid);
scatter(g,t)

Best Answer

dinfo = dir('*.txt');
for K = 1 : length(dinfo)
  thisfilename = dinfo(K).name;  
 %read the file 
end
Read about load, importdata_, textscan to load whole text file data instead of reading line by line.
