A matrix decomposition RBF algorithm: Approximation of functions and their derivatives
We propose an efficient algorithm for the approximation of functions and their derivatives using radial basis functions (RBFs). The interpolation points are placed on concentric circles and the… Expand

Numerical analysis of the MFS for certain harmonic problems
The Method of Fundamental Solutions (MFS) is a boundary-type meshless method for the solution of certain elliptic boundary value problems. In this work, we investigate the properties of the matrices… Expand

Implicit-explicit BDF methods for the Kuramoto-Sivashinsky equation
We consider the periodic initial value problem for the Kuramoto-Sivashinsky (KS) equation. We approximate the solution by discretizing in time by implicit-explicit BDF schemes and in space by a… Expand

Matrix decomposition MFS algorithms for elasticity and thermo-elasticity problems in axisymmetric domains
In this work, we propose an efficient matrix decomposition algorithm for the Method of Fundamental Solutions when applied to three-dimensional boundary value problems governed by elliptic systems of… Expand

Linearly implicit schemes for a class of dispersive–dissipative systems
We consider initial value problems for semilinear parabolic equations, which possess a dispersive term, nonlocal in general. This dispersive term is not necessarily dominated by the dissipative term.… Expand

Some Aspects of the Method of Fundamental Solutions for Certain Biharmonic Problems
In this study, we investigate the application of the Method of Fundamental Solutions for the solution of biharmonic Dirichlet problems on a disk. Modifications of the method for overcoming sources of… Expand

The under-determined version of the MFS: Taking more sources than collocation points
In this study we investigate the approximation of the solutions of certain elliptic boundary value problems by the Method of Fundamental Solutions (MFS). In particular, we study the case in which the… Expand
