What you could do quite easily is making one additional countour plot of the 
difference of the two matrices, e.g. absolute(matrix1 - matrix2).

I don't know if there is a possibility of overlaying two contours and somehow 
switching there alpha-value dynamically, which could be useful, but an 
overlay contourf of matrix1 and contour (not filled) for matrix 2 could be 
done.
