MATLAB: Block Parameters are Always Deleted

simulink

I created parameters in the block parameter options for several transfer functions and gains. I opted to save each one on 'Base Workspace'. Everytime I close the project, Matlab deletes the parameters and I have to do everything all over again.
How do I prevent that?

That is expected behavior. I don't know why it was designed that way. To avoid the problem, do either one of these:
  1. Create the variable in Model workspace, it will be saved with the model.
  2. Create the variable in a Simulink Data Dictionary, it will be saved to a .sldd file.
  3. Save the workspace variable to a .mat file before closing MATLAB. Next time, load the .mat file first.
  4. Export the workspace variable to a .m file before closing MATLAB. Next time, run the .m file first.
