The main purpose of this chapter is to show you how to work with matrices and vectors in Excel, and use matrices and vectors to solve linear systems of equations. Counter- examples are given to show that in decision making, different methods of deriving priority vectors may be close for every single pairwise comparison matrix, yet they can lead to different overall rankings. matrix with entries Rij that should be found explicitly in terms of θ, ni, δij, εijk, etc.
