Neighbors Of 2D Array - Return SmartArray With Values

I have attempted on my own many times but I am not getting any closer to a solution.

/**

* Returns a SmartArray with eight values. The values are the values stored in the 8 neighbors of the array cell at the given location in the Smart2DArray.

* Start with the neighbor to the "north" of the given cell and proceed clockwise, using -1 as the value if the neighboring cell is outside the Smart2DArray.

For example, if the array is:
1 2 3
4 5 6
7 8 9

neighbors(1, 1) should return a SmartArray with the values:
2 3 6 9 8 7 4 1
in that order.

neighbors(2,1) should return a SmartArray with the values:
3 -1 -1 -1 9 8 5 2
in that order.
