Subject svn commit: r1204270 - in /commons/proper/math/trunk/src: main/java/org/apache/commons/math/ode/nonstiff/ test/java/org/apache/commons/math/ode/events/ test/java/org/apache/commons/math/ode/nonstiff/
Date Sun, 20 Nov 2011 21:41:47 GMT
Author: luc
Date: Sun Nov 20 21:41:46 2011
New Revision: 1204270

URL: http://svn.apache.org/viewvc?rev=1204270&view=rev
Log:
Improved Dormand-Prince 8(5,3) step interpolator accuracy at step start.

The previous step is preserved and if interpolation time is in the first
half ot the step, then interpolation is based on step start, otherwise
is it based on step end. Previously, interpolation was always performed
with respect to step end.

If this trick proves useful, it will be extended to other Runge-Kutta
type step interpolators.
