报告摘要:For solving the 2D scattered data interpolation problem we develop a family of two-parameter membrane functions as the bases to construct the interpolant, which can avoid the highly ill-conditioned property by using the high-order polynomials. We begin with the boundary functions on a rectangle in the plane to construct a sequence of membrane functions with different orders of the shape functions. The polynomial, sinusoidal, exponential shape functions and maybe their weight combination are used to generate the two-parameter membrane functions. The novel method can reconstruct highly accurate function in the whole domain with less amount of interpolated data. The present method is novel and promise in the 2D scattered data interpolations.
