Why is there a value 4.000000000000001 in the cofactor matrix of problem 4? The matrix is composed entirely of integers, so the cofactors should all be integers as well.
@william .. sorry man-- i overlooked .. i've corrected it now.
sth related to the determinant function- matlab provided that answer. i didn't see that
Why is det(x)*inv(x) not working?
