MATLAB: Importing multiple text files into MATLAB

importMATLABmultiple filestext file

I am trying to import multiple text files into MATLAB and save it as a .mat file after it has been imported. It works when I do it one file at a time by using the following command, for example:
T1_1041 = importdata('20101011_114543_VIN9375_Trigger01.txt');
but when I try to save the file name into a variable and try to use the importdata function with that variable as the file name. It does not work, like below:
myfile = '20101011_114543_VIN9375_Trigger01.txt'
[files,path] = uigetfile('MultiSelect', 'on');
for n=1:length(files);
  myfile = files(n);
  files(n).data=importdata(myfile);
  save files(n).data
end
It gives an error inside the importdata function.

Your variable "files" is a cell string, therefore you need curly braces. During the loop you overwrite the original "files" by a struct. The variable "myfile" is overwritten also - it looks really confused.
[filenames, pathname] = uigetfile('MultiSelect', 'on');
filenames = cellstr(filenames);  % EDITED

for n = 1:length(filenames)
  afile = fullfile(pathname, filenames{n});  % EDITED
  data = importdata(afile);
  % Remove the file extension file the name:
  [dummy, afilename] = fileparts(filenames{n});
  save(afilename, 'data');
end
If you want to save all data in one MAT file, explain this again with more details.
