failure report to ode

failure report to ode

failure report to ode

(OP)
I am a new user of matlab and also a new member in this forum. Now i have met a problem with ode in matlab. I use ode to solve a differential equation. But there is always a failure arised, when i let the program run. It says: Warning: Failure at t=2.946368e-02.  Unable to meet integration tolerances without reducing the step size below the smallest value allowed (5.551115e-17) at time t. And then it runs no longer and at the end comes:??? Error using ==> deval
Attempting to evaluate the solution outside the interval
[0.000000e+00, 2.946368e-02] where it is defined. In the program the deval was set with the interval from 0 to 10s with together about 200 points.

So, who has maybe also met this problem before or knows, how to solve this problem. Please give me a advice. Thanks a lot.
