Hi all,
there is a function named rep which is defined as:

00036    inline label rep
00037    ( 
00038        const label i, 
00039        const label j, 
00040        const label k, 
00041        const labelList& nn 
00042    ) 
00043    { 
00044        return (k + j*nn[2] + i*nn[1]*nn[2]); 
00045    }

Does anyone knows what does this function do?
