the only thing you need to do is open the file
fid = fopen('your_file.dat');
while(1)
line = fgetl(fid);
if ~isempty(line), break, end;
%parse the line by white spaces
parsed_line = textscan(line,'%s');
% now do what you want with each line
% typecast with str2num etc ...
% or read in data lines with textscan(line,'%f')
% which will save time ...
end
file is not very hard. just spend some time playing around
and use some good'ol trial and error. Don't try to parse
the whole file while you're writing the code. just take
like the first 50-200 lines of the file and work with that.
once you're confident that you can parse at least one
record properly then try your code on the whole file.
