Derivative input 1 of 'bsjiabf2/BG/baiC/Integrator' at time 2.815980315877682 is Inf or NaN.
Stopping simulation.
There may be a singularity in the solution.
If not, try reducing the step size (either by reducing the fixed step size or by tightening the error tolerances)
这是他的错误叙述,请问错误源自何处?该怎么解决??希望能得到帮助!!谢谢。QQ93644311;邮箱afei8233@yahoo.com.cn
这应该不是代数环的问题吧?!我理解代数环是怎么一回事!!!还有如下的警告——Warning: Unable to reduce the step size without violating minimum step size of 1e-010 at time 1.000000000000014e-010.
