The discrete Fourier transform: A canonical basis of eigenfunctions
We exhibit a canonical basis of eigenvectors for the discrete Fourier transform (DFT). The transition matrix from the standard basis to defines a novel transform which we call the discrete oscillator transform (DOT for short). Finally, we describe a fast algorithm for computing in certain cases.
