Simulink - Saving Base Workspace Variables
显示 更早的评论
Is there a way to save the Simulink "base workspace" variables from the .m file? Everytime I open my model in Simulink, I need to re-inport the base workspace, but would rather have the variables saved in the model.

There are at least two other ways.
- Once all the .m files are executed, you can use save() to save the base workspace to a .mat file. Next time, you use load() to load it. This might be faster if .m files have lots of "computing" involved. On the onter hand, .m files are text and easily visible. So the choice is case dependent.
- You can transfer your variables from .m file or base workspace to a Simulink Data Dictionary (SLDD, .sld) file and then "attach" it to the model. Search document for how to use it.
In any case, there is no direct way to save all the variables directly in the Simulink model file (.mdl or .slx). And it is not a good idea to do that.
A stretch way is to copy and past the .m text to the "PreLoadFcn" of the Simulink model so you could end up with one Simulink model file that includes both the model contents and base workspace variables.
Or if you are looking for convenience, then you can type all those .m file names in the "PreLoadFcn" of the model. All you need is to open the Simulink model and all the .m files will be automatically executed.

One option is to use the Model Workspace: "Each model is provided with its own workspace for storing variable values."

That is true. In that sense, the variables are saved directly with the model in a single file.

There is also an option to have the variables stored in a .mat file:
- When the model is loaded, the workspace is initialized from a data source.The data source can be a Model file, a MAT-file, a MATLAB file, or MATLAB code stored in the model file. For more information, see Data source.
