   Public Member Functions
       SCMatrixSubblockIter (Access access)
           The access variable should be one of Read, Write, Accum, and None, with the
           SCMatrixSubblockIter:: scope operator applied.
       virtual void begin ()=0
           Start at the beginning.
       virtual int ready ()=0
           Returns nonzero if there is another block.
       virtual void next ()=0
           Proceed to the next block.
       virtual SCMatrixBlock * block ()=0
           Return the current block.
       Access access () const
           Return the type of Access allowed for these blocks.

Detailed Description

       Objects of class SCMatrixSubblockIter are used to iterate through the blocks of a matrix.

       The object must be deleted before using the matrix that owns the blocks that
       SCMatrixSubblockIter is iterating through.
