Reconstruct multiscale functions using different RBFs in different subdomains

摘要

In practice, we usually encounter many multiscale functions. For example, in the fields of condensed phase physics, computational chemistry, and nano structure. It would be very difficult to reconstruct these functions. In this paper, we will provide an efficient meshless method, we would reconstruct these functions by two or more RBFs. The efficiency would be demonstrated by numerical experiments.
