A numerical method for solving nonlinear Fredholm integro-differential equations is proposed.This method is based on hybrid function approximation.Some properties of a hybrid of block pulse functions and orthonormal Bernstein polynomials are given and utilized to reduce the problem to the solution of nonlinear algebraic equations.Numerical examples are also introduced to illustrate the effectiveness and simplicity of the present method.
