Discrete gould transform

WebWe present a new discrete transform, the Gould transform (DGT). The transform has many interesting mathematical properties. For example, the forward and inverse transform … WebThe discrete Gould transform is based on combinatorial notation described in Riordan [1, p 49]. Therefore, before presenting the transform, we will introduce the mathematical convention to facilitate the presentation of the transform. By convention, C (n,k ) n!/k!(n k )! k
