I'm kind of weak in this area, so I'm just going to shoot you a link http://tutorial.math.lamar.edu/Classes/LinAlg/Diagonalization.aspx I'm sure somebody can explain it in their own words though... @UnkleRhaukus @nbouscal

Why don't you ask a specific question? Your question is too general and it takes time to answer all aspects of it.

okay: use the diagonlization theomr to find eignevalues of A and baisis for each eignespace: A= [ 2 1 1 1 4 1 1 1 2] =[ 1 1 0 [ 3 0 0 [ 0 1 1 1 1 1 0 2 0 1 1 1 0 1 1] 0 0 3] 1 1 0]

\[ Det(A\lambda I)=\lambda ^3+8 \lambda ^221 \lambda +18=(\lambda 3)^2 (2\lambda ) \] So it has 3 as a double eigenvalue and 2.

Find X such that AX = 2 X and Y such AY =3Y Y1={1, 0, 1} Y2={1, 1, 0} X={1, 1, 1} Y1, and Y2 is a basis for the eigenspace of 3 X is a basis for the eigensapce 2
