Output missing when running Simulink model from script.

Hey everybody,
I am currently trying to run a automated simulation by running a simulink model from a matlab script. Everything works fine so far except of that the "to workspace" block doesn't return it's output to the matlab workspace when I run the simulink model with the command "sim(modelName, 'StopTime', '100');". When I click the play button of the Simulink model it does return the output to the matlab workspace.
Is there any possibility that I start the simulation from a matlab script and process the output vector right afterwards?
Thanks in advance!
Regards,
Lennart

When you use sim(), the To Workspace block writes the data into the workspace of the function that called the sim() command. That function can act on the variables such as by using assignin('base').
When you start a model from a graphics menu, the To Workspace block writes the data into the base workspace.

To Workspace can be configured to either write in the workspace of the calling function (or script) or else into the base workspace. If the expected output does not show up in the workspace of the calling function (or script) then try
evalin('base', 'whos')
to see if it showed up there.

I have the same issue, the sim() function takes the output of simulink only from the integrator.
