An Examination of Stability Criteria for Iterative Numerical Schemes Used in Solving Differential Equations
Abstract
The stability of numerical schemes for solving algebraic finite- difference equations resulting from finite-difference approximations to differential equations is discussed. It is suggested that the von Neumann method together with its stability criterion provides a reasonably simple way of determining stability. However, there are limitations in its applicability, some of which are indicated. The method is tested in two examples and an indication is given of how best to treat first- and mixed-derivative terms occurring in differential equations. (Author)
