Abstract

We consider trigonometric interpolations with shifted equidistant nodes and investigatetheir accuracies depending on the shift parameter. Two different types of interpolations arein the focus of our attention: the Krylov-Lanczos and the rational-trigonometric-polynomialinterpolations. In both cases, we find optimal shifts that provide with the best accuracy indifferent frameworks.
