Why don't you try it and find out?
Or you could read MATLAB's very helpful documentation on workspaces : When you call a script from a function, the script uses the function workspace.
This means a script can use any variables already existing in the function's workspace, and any variables it creates or alters will remain in that function's workspace. But actually I would recommend that you call another function, rather than a script (unless you have a good reason to do so). You could make this a local function too.
There are lots of other useful things to know about scripts and functions, and explanations of their main differences .
