从R2009b版本开始，MATLAB的sim函数得到了增强，提高了与并行计算的兼容性。改进的单输出格式将所有仿真结果保存到一个对象中，简化了输出变量的管理。对于与R2009a或更早版本的向后兼容，可以使用兼容语法。如果不指定任何输出参数，Simulink会根据数据导入/导出配置参数设置确定要记录的数据。

Starting with R2009b, the sim command was enhanced to provide greater compatibility with parallel computing. The improved single-output format saves all simulation results to a single object, simplifying the management of output variables.

For backward compatibility with R2009a or earlier releases, use the backward-compatible syntax:

[T,X,Y] = sim('model',Timespan, Options, UT)
[T,X,Y1,...,Yn] = sim('model',Timespan, Options, UT)
If you specify only the model argument, Simulink automatically saves the time, state, and output to the specified output arguments.

If you do not specify any output arguments, Simulink determines what data to log based on the settings for the Configuration Parameters > Data Import/Export pane. Simulink stores the simulation output either in the current workspace or in the variable ans, based on the setting for Save simulation output as a single object parameter.
