Eigen vector problem

Right, this is driving me up the walls...

0.981 , 0.019
0.019 , 0.981

is a transition matrix, I want to get to the eigenvalues and vectors.
Now I'm getting that 1 and 0.962 are the eigenvalues and that
-0.70711 , 0.70711
0.70711 , 0.70711
are the eigenvalues, but those don't make sense economically (at least I don't think they do)
as

(p(a)) = c1 (-0.70711).(1) + c2 (0.70711).962
(p(b)) = ....(.70711).........+.....(0.70711)

leads to a p(a) = p(b) = .5, which is not correct

Its grand.
Transition matrix was wrong. Stupid decimal places...

If you don't mind me asking what were you using this matrix for? What are p(a) and p(b)? Is it economics?

Yeah, its to calculate the expected probabilitiy of a future state.
