Three dimensional alternating exponential interpolation

Abstract:
Family of three dimensional alternating exponential functions is defined and various properties of three dimensional alternating exponential functions are presented. Corresponding discrete Fourier transform is introduced with the emphasis given to practical application demonstrated on several examples.
