Abstract :
In this paper, Block Pulse Functions and their operational matrices are used to solve Volterra-Fredholm integro-differential equation (VFIDE). First the equation is integrated over interval [0, x] and then Block Pulse functions are used to obtain numerical solution. Some theorems will prove convergence of the method. Some numerical examples are included to illustrate accuracy of the method.
