### Description

This example currently does nothing.

### Code

MatlabEngineFilter.cxx

    //need to set VTK_USE_MATLAB_MEX ON

    #include <vtkSmartPointer.h>
    #include <vtkMatlabEngineFilter.h>

    int main(int argc, char *argv[])
    {
      vtkSmartPointer<vtkMatlabEngineFilter> matlabFilter =
          vtkSmartPointer<vtkMatlabEngineFilter>::New();

      return EXIT_SUCCESS;
    }

### Download and Build MatlabEngineFilter

Click here to download MatlabEngineFilter and its CMakeLists.txt file. Once the tarball MatlabEngineFilter.tar has been downloaded and extracted,

    cd MatlabEngineFilter/build

If VTK is installed:

    cmake ..

If VTK is not installed but compiled on your system, you will need to specify the path to your VTK build:

    cmake -DVTK_DIR:PATH=/home/me/vtk_build ..

Build the project:

    make

and run it:

    ./MatlabEngineFilter
