From your error message I would guess that the matrix created for i1 is of different size from that of i2, and consequently matlab complained at the line
k=abs(j1-j2);
since j1 and j2 would also be of different sizes. You can easily check this by displaying the respective sizes of i1 and i2 in your code.
