How do I run a script from a GUI that will run in the 'base' workspace?

I have a simulink model that uses a lot of variables from the base workspace. Now I am making a GUI that runs the model, but I want to be able to reinitialize the base workspace by calling the script that does this. But I want to do it from the GUI. How do I run a script as if in the base workspace so that it populates all the variables there? I could use assignin('base', var, reinitvar), but this would be extremely tedious for all the variables. Is there another option?

Adam has asked the most important question. Making variables magically appear (or evalin-ing) in workspaces is buggy and slow. So why do this? Keep workspaces distinct, and pass variables properly.

It is because Simulink "From Workspace" blocks get their values from the Base workspace if the model is invoked by double-clicking on it or by using the menus. However, if the model is invoked by a MATLAB function running the sim() command, then From Workspace gets its variables from the workspace of the function that has the sim() call. I gather, however, that it is not uncommon for From Workspace blocks to somehow be configured to look only in the Base workspace.

Simulink bypasses normal workspace encapsulation sometimes :(
