I second the call for a more concrete implementation, but if you want the results of the functions in c3 to be responsive to the values of c1 and c2 (i.e., if you change r1c1, r1c3 returns a different value), it might be worth encapsulating the whole thing in an object and making the c3 functions properties, which is Python for 'preprocessed attributes.'
