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?

在 MATLAB Online 中打开

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);
