In Matlab, what is ~m file?

Question

What does the ' ~ ' sign mean at the end of the file name?

BONUS QUESTION: How can I add files to the git repository without adding those '~' files?

Answer 1

That is a backup file, and if I am not mistaken it is actually from unix system and not matlab. On windows the backup files are *.asv. If you close your file the backup should disappear.

If you asking about version control, I would suggest you ignore all backup files by adding a like to .gitignore as follows: *.m~.
