从Matlab函数运行Simulink(Run Simulink from Matlab function)

 我正在使用FastRestart运行Simulink，因为我需要多次启动和停止模拟更改参数。 当我从主脚本运行Simulink时，没有问题。 但是，只要我使脚本成为一个函数，以便我可以为不同的输入数据运行它，我就会得到一个与Simulink明显相关的错误，而不是在函数中看到Matlab工作区。 
 
 更确切地说，假设sfile是我的Simulink文件，然后在Matlab中初始化我需要的所有变量之后运行以下行： 
 
load_system(sfile);
set_param(sfile,'FastRestart','on');
set_param(sfile,'SaveFinalState','on');
set_param(sfile,'SaveCompleteFinalSimState','on');
set_param(sfile,'SimulationCommand','update');
 
 在最后一行，我得到了Simulink无法识别mdl.tStep （这是时间步长）的错误，因为mdl不是公认的结构。 事实上，如果我从主脚本运行Simulink，一切都很好。 
 
 现在，在过去，我会用 
 
options = simset('SrcWorkspace','current');
 
 但是，我认识的专家建议我反对simset （因为它可能会在将来被弃用），并鼓励我使用set_param 。 我已经在线查找了set_param的选项，但是我找不到Matlab工作区的设置。 
 
 任何帮助将不胜感激。 先谢谢你！ 

I am running Simulink using FastRestart, as I need to start and stop the simulation multiple times changing parameters. When I run Simulink from the main script, there are no problems. However, as soon as I make the script a function so that I can run it for different input data, I get an error that is clearly related to Simulink not seeing the Matlab workspace within the function.
 
To be more precise, say sfile is my Simulink file, then I run the following lines AFTER having initialized all variables I need in structures in Matlab:
 
load_system(sfile);
set_param(sfile,'FastRestart','on');
set_param(sfile,'SaveFinalState','on');
set_param(sfile,'SaveCompleteFinalSimState','on');
set_param(sfile,'SimulationCommand','update');
 
At the last line, I get the error that Simulink does not recognize mdl.tStep (which is the time step), as mdl is not a recognized structure. In fact, it is and if I run Simulink from the main script everything is fine.
 
Now, in the past, I would have used 
 
options = simset('SrcWorkspace','current');
 
However, an expert I know has advised me against simset (as it may get deprecated in the future) and encouraged me to use set_param instead. I have looked up the options for set_param on-line, but I could not find the setting for the Matlab workspace. 
 
Any help would be greatly appreciated. Thank you in advance!
