Solving the Poisson Equation by an Interval Difference Method of the Second Order
Tomasz Hoffmann, Andrzej Marciniak · Computational Methods in Science and Technology · 2013
The paper deals with an interval difference method for solving the Poisson equation based on the conventional central-difference method.We present the interval method in full details.The method is constructed in such a way that the exact solution is included in the interval solution obtained.Some numerical results obtained in floating-point interval arithmetic are also presented.
