Hello Huidan,
There is no way for me to tell what is the problem. The code is
telling you either that the problem as stated is not well-posed, or
that the method options or other inputs are not suitable for it.
You need to find out why it is taking stepsizes that are too small.
Letting it take more steps is not a solution.
