 Sep 24 awarded Autobiographer Apr 29 comment Eigenvector of matrix of equal numbers I still don't get how you got (-1, 1, 0) and (-1, 0, -1). I know it's the right answer, but I how do you get it from x1+x2+x3 = 0? Apr 29 comment Eigenvector of matrix of equal numbers I understand all of this. I still don't get how you'd get to (-1, 1, 0) and (-1, 0, -1) from $x_1 + x_2 + x_3 = 0$ Apr 28 awarded Critic Apr 28 comment Eigenvector of matrix of equal numbers So to make it in terms of $x_1$, you set $x_1$ to 1 and set once $x_2$ to zero, and in the other vector, $x_3$ to zero (the other would be -1 as the equation $x_1 = -x_2-x_3$ shows)? Apr 28 comment Eigenvector of matrix of equal numbers I know. This matrix has 3 eigenvalues, two of which are repeated, so I can generate the third from the second. But how would I find the second? (I already found the first corresponding to the single real-valued eigenvalue). This does not answer how to find it.
