  This paper provides a numerical approach for solving the linear stochastic
Volterra integral equation using Walsh function approximation and the
corresponding operational matrix of integration. A convergence analysis and
error analysis of the proposed method for stochastic Volterra integral
equations with Lipschitz functions are presented. Numerous examples with
available analytical solutions demonstrate that the proposed method solves
linear stochastic Volterra integral equations more precisely than existing
techniques. In addition, the numerical behaviour of the method for a problem
with no known analytical solution is demonstrated.
