MatLab supports multidimensional arrays natively, so, unless some aspect
of your algorithm greatly benefits from it, you are probably better off
not manually doing the 2-D to 1-D indexing conversion.

If you must use a 1-D array and do the indexing conversion, perhaps it
would be better to use the MatLab function sub2ind() to make the code a
bit more readable:

>> siz=[16 32768];
>> % ... iterate over J and K
>> J1=sub2ind(siz,J,K);
