INTERPOLATION WITH EXPONENTIALLY FITTED 2ND-ORDER C1-SPLINE FUNCTIONS

[摘要] Following the ideas of Mettke et al. (1982), some results are developed for the interpolation with nonpolynomial spline functions. These splines may be called exponentially fitted because they belong piecewise to the kernel of some differential operators. The interpolation and spline grids coincide.
