Lecture 26: Complex matrices; fast fourier transform

The Fourier matrices have complex valued entries and many nice properties. This session covers the basics of working with complex matrices and vectors, and concludes with a description of the fast Fourier transform.

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.
