On approximate approximations using Gaussian kernels. (English) Zbl 0838.65005
The authors study an application of a new approximation method characterized by a very accurate approximation in a certain range relevant for numerical computations to the approximation of multivariate functions using Gaussian kernels. The construction of local high-order quasi-interpolation formulas is given.
