Forgive me if I missunderstand a basic Eigensystem but when I present the following matrix to most any other LinearAlgebra system:
1 3 1 1 2 2 1 1 3 I get an answer like: //$values //[1] 5.000000e+00 1.000000e+00 -5.536207e-16 //$vectors // [,1] [,2] [,3] //[1,] 0.5773503 -0.8451543 -0.9428090 //[2,] 0.5773503 -0.1690309 0.2357023 //[3,] 0.5773503 0.5070926 0.2357023 But R gives me: //$values //[1] 5.000000e+00 1.000000e+00 -5.536207e-16 //$vectors // [,1] [,2] [,3] //[1,] -0.5773503 -0.8451543 -0.9428090 //[2,] -0.5773503 -0.1690309 0.2357023 //[3,] -0.5773503 0.5070926 0.2357023 The only difference seems to be the sign on the first eigen vector. What am I missing?
