Many calculations become simpler when performed using orthonormal vectors or orthogonal matrices. In this session, we learn a procedure for converting any basis to an orthonormal one.

These video lectures of Professor Gilbert Strang teaching 18.06 were recorded in Fall 1999 and do not correspond precisely to the current edition of the textbook. However, this book is still the best reference for more information on the topics covered in each lecture.
