“The Matrix Resurrections,” a Warner Bros. release, is rated PG-13 by the Motion Picture Association of America for violence and some language. Running time: 148 minutes.

Today's languages were each designed with different goals in mind. Matlab was built for matrix calculations, and it's great at linear algebra. The R language is meant for statistics.
