چكيده فارسي :
This paper formulates a radial basis functions (RBFs) collocation method for the numerical solution of the
nonlinear Korteweg-de Vries Burgers’ (KdVB) equation. Three radial basis functions are used in this method.
The accuracy of the method is assessed in terms of the errors in and root mean square (RMS), number of
nodes in the domain of influence, parameter dependent RBFs time and spatial steps length. Numerical example
is given to confirm the good accuracy of the method for solving complicated nonlinear partial differential
equations. In this work one test problem is studied.
