So apparently you solved your other question? We don't know anything about what your files contain, what format they are or anything else. I don't know about other frequent contributors here, but I'm not a mind reader.

Have a read here and here. It will greatly improve your chances of getting an answer.

Here is read about how to batch process files in MATLAB: http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F.

Here is a general idea. You can read the content of your file one by one, in a for loop, using either fileread(), textscan, tableread(), csvread() and several other function available in MATLAB. Which function to use depends on the content of your file. Then after reading one file, convert it to a desirable format and save it a cell array.

files = dir('*.dat')
data = cell(1, length(files);
for i=1:length(files)
  filename = files(i).name
  % read filename using an appropriate function depending on your data.
  data{i} = processedData; % here processed data obtained after reading the file.
end
