Discrete Weierstrass Fourier Transform and Experiments

Published 12 Feb 2015 in math.NA | (1502.07734v4)

Abstract: We established a new method called Discrete Weierstrass Fourier Transform, a faster and more generalized Discrete Fourier Transform, to approximate discrete data. The theory of this method as well as some experiments are analyzed in this paper. In some examples, this method has a faster convergent speed than Discrete Fourier Transform.
