I have text file with three columns and a lot of rows. The third column has a value of either 1 or 0. I want to choose the rows for which the third column is 0 and write it in a new text file.

Probably the easiest, assuming your text file format is straightforward to decode:

filecontent = readtable('c:\somewhere\somefile.txt');  %readtable should be able to figure out the format on its own
filteredcontent = filecontent(filecontent{:, 3} == 0, :);  %keep content where 3rd column is 0
writetable(filteredcontent, 'c:\somewhere\newfilename.txt');  %and save
