//
// *****************************************************************************
//
// CLASS DESCRIPTION (MFnMatrixData)
//
// MFnMatrixData allows the creation and manipulation of MMatrix data objects
// for use in the dependency graph.
//
// If a user written dependency node either accepts or produces MMatrix, then
// this class is used to extract or create the data that comes from or goes to
// other dependency graph nodes. The MDataHandle::type method will return
// kMatrix when data of this type is present. To access it, the
// MDataHandle::data method is used to get an MObject for the data and this
// should then be used to initialize an instance of MFnMatrixData.
