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.
