Convergence Results for the MATLAB ode23 Routine

open access: yes, 1998
We prove convergence results on finite time intervals, as the user-defined tolerance ΓΈ ! 0, for a class of adaptive timestepping ODE solvers that includes the ode23 routine supplied in MATLAB Version 4.2.

Stable Spectral Methods For Conservation Laws On Triangles With Unstructured Grids

open access: yes, 1997
. This paper presents an asymptotically stable scheme for the spectral approximation of linear conservation laws defined on a triangle. Lagrange interpolation on a general two-dimensional nodal set is employed and, by imposing the boundary conditions ...

Efficient simulation of a slow-fast dynamical system using multirate finite difference schemes

open access: yes, 2016
We consider a system of ordinary differential equations describing a slow-fast dynamical system, in particular, a predator-prey system that is highly susceptible to local time variations.

On the Construction of Stiffly Accurate and B-Stable Runge-Kutta Methods

open access: yes, 1996
. In the solution of stiff ODEs and especially DAEs it is desirable that the method used is stiffly accurate and B-stable. In this paper guidelines for the construction of Runge-Kutta methods with these properties are presented.

On Roots And Error Constants Of Optimal Stability Polynomials.

open access: yes, 1998
. Optimal stability polynomials are polynomials whose stability region is as large as possible in a certain region, here the real-negative axis. We are interested in such polynomials wich in addition, obey a certain order condition.

Nonlinear Optimization Approach to Construction of General Linear Methods of High Order

open access: yes
. We describe the construction of diagonally implicit multistage integration methods of order and stage order p = q = 7 and p = q = 8 for ordinary differential equations.
