I am employing the Ode15s subroutine of Matlab for solving some differential equation. But I have obtained the next error message:(adsbygoogle = window.adsbygoogle || []).push({});

"Warning: Failure at t=-6.718807e-001. Unable to meet integration tolerances without reducing the step size below the smallest value allowed (2.387000e-015) at time t.

(Type "warning off MATLABde15s:IntegrationTolNotMet" to suppress this warning.)

> In C:\MATLAB6p5\toolbox\matlab\funfun\ode15s.m at line 743"

I don't know what does it mean, and how can it be solved. If I change the ode solver it remains happening the same.

Thanks
