As you look through the OpenSim doxygen or if you look at OpenSim API examples, in C++, you may see objects/classes with names like Array_<double> or Vec<3>. These are called templatized classes; this is another functionality that exists in C++ to help programmers simplify and reuse common code. But this doesn't exist in Matlab. So we have created scripting versions of the most commonly used templatized classes. You can find a list of all of these on the page Scripting Versions of OpenSim C++ API Calls. If you see a class name with angle brackets (< >), you can look it up on this page to find the class name to use in Matlab.

Adding Geometry Paths to Matlab 

...

Alternatively, a 'workaround' that if you are not visualizing the model is to remove the geometry from the model. This should only be used if you are doing many model instantiations or initSystem() calls and don't need to visualize the model.

Outputs

OpenSim 4.0 uses component outputs and reporters to collect variables of interest and print them to file. To display the output names for a component, use the method getOutputNames();
