matrix computation

Dear Sir: I try to learn to use the linear algebra in maple. I try to compute the following matrices. restart; assume(a>0,b>0,c>0); with(LinearAlgebra): M:=Matrix([[a, 0],[0, b]]); K:=Matrix([[c,-c],[-c,c]]); V:=Eigenvectors(K,M); X:=V[2]; Multiply(Multiply(X^%T,M),X); I expect that the final result should be the indentity matrix. However, it does not produce what I expect. Please give me some advice to get the identity matrix. Thank you.
