             Summary: Add fast single-step method for fixed-step ODE integrators
                 Key: MATH-1119
                 URL: https://issues.apache.org/jira/browse/MATH-1119
             Project: Commons Math
          Issue Type: Improvement
    Affects Versions: 3.2
            Reporter: Luc Maisonobe
            Assignee: Luc Maisonobe
            Priority: Minor
             Fix For: 3.3


Sometimes, very fast computation of only a few steps of an ODE integrators are needed and embedded in much larger loops. Setting up a full-blown integrators with all its bells and whistles is cumbersome in this case where only the final state is desired.

A stripped-down version of the ODE integrator using only the Butcher arrays from Runge-Kutta integrators would be nice.
