چکیده (انگلیسی):

In this paper, we obtain stochastic operational matrix of block pulse functions on
interval [0, 1) to solve stochastic Volterra–Fredholm integral equations. By using block pulse functions and their stochastic operational matrix of integration, the stochastic Volterra–Fredholm integral equation can be reduced to a linear lower triangular system which can be directly solved by forward substitution. Weprove that the rate of convergence is O(h). Furthermore, the results show that the approximate solutions have a good degree of accuracy.
