I've been doing some work with coupled ODEs in Matlab. I've been using ODE15s, and calculating the solutions of 40 coupled equations between t=0.....0.01, but Matlab seems to be calculating far more accurately than I want, it's taking 40 minutes to produce a solution and determining the function at over a million points on the domain.(adsbygoogle = window.adsbygoogle || []).push({});

Any suggestions on how to make things a little less precise? If I only had one of every thousand of the points it calculates, I'd be happy.
