摘要：

Purpose - The purpose of this paper is to show that the meshless method based on radial basis functions (RBFs) collocation method is powerful, suitable and simple for solving one and two dimensional time fractional telegraph equation. Design/methodology/approach - In this method the authors first approximate the time fractional derivatives of mentioned equation by two schemes of orders O (tau(3 - alpha)) and O (t(2 - alpha)), 1/2<alpha<1, then the authors will use the Kansa approach to approximate the spatial derivatives. Findings - The results of numerical experiments are compared with analytical solution, revealing that the obtained numerical solutions have acceptance accuracy. Originality/value - The results show that the meshless method based on the RBFs and collocation approach is also suitable for the treatment of the time fractional telegraph equation.
