A multiquadric quasi-interpolation with linear reproducing and preserving monotonicity

Journal of Computational and Applied Mathematics, 2009
The authors develop a multiquadric quasi-interpolation which has the properties of linear reproducing and preserving monotonicity. Moreover, its approximation error is given by a theoretic analysis and illustrates the effect by means of two examples.

Using adomian’s decomposition and multiquadric quasi-interpolation methods for solving Newell–Whitehead equation

Procedia Computer Science, 2011
AbstractIn this paper, we study numerical solution of the Newell–Whitehead equation (NWE) by using Adomian’s method (ADM) and Multiquadric quasi-interpolation method. ADM has been extensively used to solve linear and nonlinear problems arising many interesting physical and engineering applications.
