sim command and to workspace logging

I am trying to run a model with the following script:

Test.Config.StartTime = '0.0'; 
Test.Config.StopTime = '100.0'; 
Test.Config.SolverType = 'Fixed-step'; 
Test.Config.Solver = 'FixedStepDiscrete'; 
Test.Config.FixedStep = '1.0';

sim('TH_CrossProduct',Test.Config);

This model has a 'To Workspace' block that is supposed to be logging a timeseries to a variable called 'Test_Output'. However, using the script above, I do not get a variable called 'Test_Output', I get a 'Simulink.SimulationOutput' object which contains 'Test_Output' assigned to 'ans'. But if I run the model using the following:

sim('TH_CrossProduct')

I do get a timeseries assigned to 'Test_Output'. Because of this, I am assuming that there is some parameter that needs to be passed via the 'Test.Config' structure to the model. However, I have no idea what this might be. Can anyone provide any help?

Thanks,

Ryan

As described on this page of the documentation, SIM returning a Simulink.SimulationOutput object is the new syntax. Getting timeseries objects directly is only possible via the Backward Compatible syntax of the SIM command, so I think you might be able to get what you need by passing in the configuration parameters as a SIMSET:

opts = simset(simget('TH_CrossProduct'),'StartTime', '0.0', ...)
sim('TH_CrossProduct', opts)

However, this syntax still exists only for the sake of backwards compatibility, so you might be better advised to use the new syntax unless your code is expected to be executed in older versions of MATLAB.
