The function CellOf2DMat retrieves the cell value of the two-dimensional matrix of the workspace addressed by MatIdx and the cell coordinates ix and iy, and returns it in the variable parameter Value. The cell coordinates are 1-based.
The function returns one of the following error codes:
0 ... everything OK, Value is valid
-1 ... MatIDx is out of bounds
-2 ... ix is out of bounds
-3 ... iy is out of bounds
||The valid range of cell indices can be obtained by the function GetDims2DMat.
