In this paper, we use a non-polynomial spline method to develop a numerical technique for solving linear fourth-order boundary-value problems which are first reduced to a system of second-order boundary-value problems. Three numerical examples are considered to demonstrate the usefulness of the method and to show that the method converges with sufficient accuracy to the exact solutions.


Key words: Cubic spline, non polynomial spline, boundary-value problems, system of equations.
