关于SIMIULINK的菜鸟问题

happydzps

我想在COMMAND WINDOWS用指令来控制SIMULINK中的电路图进行仿真，电路图保存名为nn,已经把仿真设置成TO WORKSPACE了，错误信息和电路图如下：
>> sim('nn')
??? Error using ==> sim
--> Error evaluating expression '[t, u]' for 'External Inputs' specified in the Configuration Parameters dialog for block diagram 'nn'. It must be possible to completely evaluate expressions in block-diagram parameter fields either in the model or source workspace.
Error in model and source workspaces: Error using ==> sim
Undefined function or variable 't'.
--> Error evaluating element '1' in list of external inputs specified in Configuration Parameters dialog. External inputs may be specified as either (a) a list of matrices and structures or (b) a single MATLAB expression or function.

哪位朋友能解释一下，直接用sim('文件名‘）不能对电路图进行仿真吗？

可以仿真吧，但电路图里面的示波器要换成输出接口模块，在模块库sinks里面找，还有命令要有返回值[t,u],试一下吧。
