Circumventing the Ill-conditioning Problem with Multiquadric Radial Basis Functions: Applications to Elliptic Partial Diierential Equations
Madych and Nelson(1990) proved Multiquadric (MQ) mesh-independent Radial Basis Functions (RBFs) enjoy exponential convergence. The primary disadvantage of the MQ scheme is that it is global, hence the coe cient matrices obtained from this discretization scheme are full. Full matrices tend to become progressively more ill-conditioned as the rank increases. In this paper, we explore several techn...
متن کاملThe use of radial basis functions by variable shape parameter for solving partial differential equations
In this paper, some meshless methods based on the local Newton basis functions are used to solve some time dependent partial differential equations. For stability reasons, used variably scaled radial kernels for constructing Newton basis functions. In continuation, with considering presented basis functions as trial functions, approximated solution functions in the event of spatial variable wit...
متن کاملMultiquadric Radial Basis Function Approximation Methods for the Numerical Solution of Partial Differential Equations
ii Preface Radial Basis Function (RBF) methods have become the primary tool for interpolating multidimensional scattered data. RBF methods also have become important tools for solving Partial Differential Equations (PDEs) in complexly shaped domains. Classical methods for the numerical solution of PDEs (finite difference, finite element, finite volume, and pseudospectral methods) are based on p...
متن کاملSolving Partial Diierential Equations by Collocation with Radial Basis Functions
Motivated by 5] we describe a method related to scattered Hermite interpolation for which the solution of elliptic partial diierential equations by collocation is well-posed. We compare the method of 5] with our method. x1. Introduction In this paper we discuss the numerical solution of elliptic partial diierential equations using a collocation approach based on radial basis functions. To make ...
متن کاملThe role of the multiquadric shape parameters in solving elliptic partial differential equations
K e y w o r d s E l l i p t i c PDEs, Generalized multiquadries, Different shape parameters. 1. I N T R O D U C T I O N The interest in meshfree methods to solve PDEs has grown considerably in the past 15 years. The two principal reasons are: (1) mesh generation over twoand three-dimensional complicated domains may require weeks or months to produce a well-behaved mesh, and (2) the convergence ...
