摘要: Approximation properties of the expansions ∑k∈ℤdLf(M−j⋅)(−k)φ(Mjx + k), where L is a linear differential operator and M matrix dilation, are studied. The sampling special case such expansions. Error estimations in Lp-norm, 2 ≤ p ≤∞, given terms Fourier transform f. approximation order depends on smoothness f, L, Strang–Fix condition for φ M. A wide class including both band-limited compactly supported functions considered, but compatibility with required. Such may be useful engineers.
