    If the underlying AccessAnyD data structure was created as 4x5x7x8, it can be viewed as 7x8 4x5 matrices. The dimensions of the MatrixView would be 4x5, and the index returned by this method indicates which of 7x8 matrices the view currently points to. The range of these indices would be 0-55.
    
    Returns:
    
    The index of the matrix (which matrix are we currently viewing).
