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.

    • It can also be integrated, and can be used as the basis for doing Fourier transforms. Completely useless as far as I've researched, but curious nonetheless. Here's an example paper: https://arxiv.org/abs/1502.07734
