Discrete Transforms and Orthogonal Polynomials of (Anti)symmetric Multivariate Sine Functions [PDF]

Entropy, 2018
Sixteen types of the discrete multivariate transforms, induced by the multivariate antisymmetric and symmetric sine functions, are explicitly developed. Provided by the discrete transforms, inherent interpolation methods are formulated.
