显示 更早的评论
hello people,
i need to edit a text file (example.in) with I/O functions but matlab doesn't support .in files so i need to change the extension to .txt and afterwards back to .in. how is that possible?
thanks a lot Cyros

Dear Cyros,
what do you mean "matlab doesn't support"? You can open a file with random extension by fopen('filename.extension') and then use all I/O functions with the fid provided by fopen.
Best regards,
Michael

I don't know what your code is, but when I save a textfile "example.in" containing just the line "1" and then open the file, I get exactly the answer "1":
fid=fopen('example.in');fgetl(fid), fclose(fid);
ans =
1
fid=-1 usually means that the file is not found. Maybe you didn't give the correct path to the file or have a typo in the filename.
Best regards,
Michael
