Any symmetric matrix A has an eigenvector. Remark: In the end, we will see that in fact A will have a lot more than just one eigenvector, but since the proof of (i) ) (iii) is ultimately done by a kind of induction, we need to produce a rst eigenvector to \get started". It is not at all the case that an arbitrary matrix has an eigenvector. Let H be an N × N real symmetric matrix, its off-diagonal elements H ij, for i < j, being independent identically distributed (i.i.d.) random variables with mean zero and variance σ > 0, i.e. 〈H ij ⃒=0, and 〈H ij 2 ⃒=σ 2 ≠ 0.

A positive deﬁnite matrix is a symmetric matrix with all positive eigenvalues. Note that as it’s a symmetric matrix all the eigenvalues are real, so it makes sense to talk about them being positive or negative.

Harmonic Analysis on Symmetric Spaces-Higher Rank

For example, A = [ 3 2 4 2 0 − 5 4 − 5 1 ] ; A ′ = [ 3 2 4 2 0 − 5 4 − 5 1 ] A matrix is symmetric when the element in row i and column j is identical to the element in row j and column i, and the values of the main diagonal of the matrix can be any. Thus, the main diagonal of a symmetric matrix is always an axis of symmetry, in other words, it is like a mirror between the numbers above the diagonal and those below.
