There are three locations to store model data:
  • Base workspace
  • Model workspace
  • Data dictionary
Find more info here on the comparison between these three, and when each storage location is used.
  • There is only one base workspace per MATLAB client. (when using the Parallel Computing Toolbox, each worker has its own base workspace)
  • Each Simulink model has its own model workspace.
  • You can have many Data dictionaries which can reference eachother

In MATLAB, you have your base workspace and then a workspace for each function called.
When debugging a script or function, you can inspect the available workspaces in the Function Call Stack (see here).

The global workspace is another one.
So one base workspace, one global workspace, one workspace per executing function.
As well, each function can have persistent variables which could potentially be considered a workspace associated with with the JIT compiled version of the function.
Anonymous functions that refer to variables other than the parameters, have a workspace to hold static copies of the value of the variable as of the time the function handle was built.

Another common one is the function workspace, which is created when the function is entered and destroyed when the function is exited. see the Help document of evalin() and assignin().
