/**
* @class vtkMatlabMexAdapter
* @brief This is a utility class to convert VTK array
* data to and from the Matlab mxArray format. It is used with the Matlab
* Mex and Matlab Engine interfaces.
*
*
*
* The default behavior of each function is to perform a deep copy of the
* data. Set the ShallowCopy argument to true to use the block of memory
* that has already been allocated by either VTK or Matlab. The result of
* a shallow copy will produce the transpose of the data in the new system,
* because VTK uses row major ordering and Matlab uses column major ordering
* for data.
*
* VTK data structures created by this class from Matlab types are stored in
* array collections and freed when the class destructor is called. Use the
* Register() method on a returned object to increase its reference count by one,
* in order keep the object around after this classes destructor has been called.
* The code calling Register() must eventually call Delete() on the object to free
* memory.
