Abstract
When considering approximation of continuous periodic functions f: R d → R by blending-type approximants which depend on directions ξ1,…,ξν ∈ R d directional moduli of smoothness (1) are appropriate measures of smoothness of /. In this paper, we introduce equivalent directional K- functionals. As an application, we obtain a result on the degree of approximation by certain trigonometric blending functions.
