Abstract:In this paper, we developed a meshless collocation method by using barycentric rational interpolation basis function based on the Chebyshev to deduce the scheme for solving the Helmholtz equation defined in arbitrary domain with complex boundary shapes. Firstly, the spatial variables and their partial derivatives are treated by interpolation basis functions, and the collocation method for solving second order differential equations is established. Then the differential matrix is used to simplify the differenti… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
