This study investigates functional Volterra integral equations. Specific conditions are imposed to guarantee the existence and uniqueness of the solution to this equation in the space of square integrable functions. Subsequently, employing the Euler operational matrix and the collocation method, an approximation to the solution is derived. This methodology converts the functional integral equation into a system of nonlinear algebraic equations, which are then solved using conventional numerical methods or iterative methods.
