31. Eigenvectors of Circulant Matrices: Fourier Matrix
MIT 18.065 Matrix Methods in Data Analysis, Signal Processing, and Machine Learning, Spring 2018 Instructor: Gilbert Strang View the complete course: https://ocw.mit.edu/18-065S18 YouTube Playlist: • MIT 18.065 Matrix Methods in Data Analysis... This lecture continues with constant-diagonal circulant matrices. Each lower diagonal continues on an upper diagonal to produce n equal entries. The eigenvectors are always the columns of the Fourier matrix and computing is fast.
