This is not twitter, so please omit the # in the tags. The tags are a comma separated list of terms, which should help to find the topic of your question. Now this is found, if any other user has a problem concerning "#text #export #dlmread #data #dlmwrite #matrix #matrice", but this is very unlikely.

The question is not clear. What did you post here? In which form is it stored in your code? What is the wanted result?

Dear Simon, this is the attached text file. Pleases advice on how to export it to matlab as matrix as code. Ty!

To answer your question, it's as simple as reading the documentation on fprintf or dlmwrite

The text file can be read in with fscanf or fgetl , and then parsed out with regexp or strfind to be then written with fprintf or dlmwrite.

Example of using regexp to obtain number. **note does not detect the - sign

fileID = fopen('track.txt');

pat = '((\d+,)*\d+(\.\d*))' 

while ~feof(fid)
    line = fgetl(fileID);
    n = regexp(line, pat, 'match')
end

fclose(fileID);
