Abstract: In this joint work with Jeffrey Geronimo and Chung Wong we study the asymptotics of the Fourier coefficients of 1/|p|^2, where p is a two variable polynomial without roots in the closed ...

A set of functions are presented for Octave/MATLAB that allow easy, consistent, and properly scaled DFT/FFT analysis of signals and noise. The techniques and functions presented are easily translated ...
