We show that there exist classes of explicit numerical integration methods that can handle very stiff problems if the eigenvalues are separated into two clusters, one containing the “stiff,” or fast,… (More)

We want to deduce, from a sequence of noisy two-dimensional images of a scene of several rigid bodies moving independently in three dimensions, the number of bodies and the grouping of given feature… (More)

In this paper we introduce s-step Conjugate Gradient Method for Symmetric and Positive Definite (SPD) linear systems of equations and discuss its convergence. In the s-step Conjugate Gradient Method… (More)

We consider dynamical systems possessing an attracting, invariant “slow manifold” that can be parameterized by a few observable variables. We present a procedure that, given a process for integrating… (More)

An integration technique for the automatic solution of an initial value problem for a set of ordinary differential equations is described. A criterion for the selection of the order of approximation… (More)

This subroutine integrates a set of up to N ordinary differential equations one step of length H, where H may be specified by the user, but is controlled by the subroutine to control the estimated… (More)

We present a time-stepper based approach to the \coarse" integration and stability/bifurcation analysis of distributed reacting system models. The methods we discuss are applicable to systems for… (More)

Recent developments in multiscale computation allow the solution of coarse equations for the expected macroscopic behavior of microscopically evolving particles without ever obtaining these coarse… (More)

Runge-Kutta-like formulas which enable a multmtep method to start or restart at a high order after lust one Runge-Kutta (RK) step are presented. These formulas greatly improve the efficiency of… (More)
