matlab运行时出现的错误请教高手
??? Error using ==> sim Derivative input 25 of 'shiyan/)' at time 0.2177777777777778 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). 是模型错误还是matlab的设置原因呢？ 换另外一个模型就可以运行。谢谢高手指点。。 提问之前注意搜索，可以参考此贴http://forum.simwe.com/thread-58397-1-1.html。
