Abstract
This article is an attempt to obtain the numerical solution of functional linear Voltrra two-dimensional integral equations using Radial Basis Function (RBF) interpolation which is based on linear composition of terms. By using RBF in functional integral equation, first a linear system ΓC = G will be achieved; then the coefficients vector is defined, and finally the target function will be approximated. In the end, the validity of the method is shown by a number of examples.
