I see. I have never thought about factor with complex numbers like that.

(*Norm of Eigenvectors from Eigenvalues*)
(*start*)
Clear[nn, t, n, k, M, x];
nn = 11;
t[n_, 1] = 1;
t[1, k_] = 1;
t[n_, k_] :=
t[n, k] =
If[n < k,
If[And[n > 1, k > 1], -Sum[t[k - i, n], {i, 1, n - 1}], 0],
If[And[n > 1, k > 1], -Sum[t[n - i, k], {i, 1, k - 1}], 0]];

T = Table[Table[t[n, k], {k, 1, nn}], {n, 1, nn}];
HermitianMatrixQ[T]

TableForm[A = Table[Table[T[[n, k]], {k, 1, nn}], {n, 1, nn}]];
lambdaA = N[Eigenvalues[A]];
TableForm[M = Table[Table[T[[n, k]], {k, 1, nn - 1}], {n, 1, nn - 1}]];
I programmed the formula from Tao's blog. I had trouble with the exponent of the norm being negative instead of positive.
Does anyone know how to get the eigenvectors, given the norm and this formula?

A simple userscript to enable linking to specific parts of a documentation page: github.com/lukas-lang/MathematicaDocLinker (I finally got tired of manually extracting the anchor id using "Inspect element"...)

very nice, works like a charm!
would it be possible to have it copied to the clipboard on click? If not, it isn't much trouble to just right-click and "Copy Link Address"

@JasonB. Good point - I have updated the extension, so now the link is copied to the clipboard instead (the old version is still available, see the Readme for more information):
