A REGULARIZATION METHOD FOR DISCRETE FOURIER POLYNOMIALS

[摘要] In this paper we present a regularization method for discrete Fourier polynomials in one and two variables. The easy relation between the discrete Fourier coefficients and those of the regularized polynomial is proved. A good automatic choice of the regularization parameter sigma is proposed and some numerical results are presented.
