The normalized vector of →u u → is a vector that has the same direction than →u u → and has a norm which is equal to 1. Take u₁ = v₁ and set e₁ to be the normalization of u₁ (the vector with the same direction but of length 1 ). For if Ax = λx and Ay = µy with λ ≠ µ, then yTAx = λyTx = λ(x⋅y).But numbers are always their own transpose, so yTAx = xTAy = xTµy = µ(x⋅y).So λ = µ or x⋅y = 0, and it isn't the former, so x and y are orthogonal. It will find the eigenvalues of that matrix, and also outputs the corresponding eigenvectors. We can also make the incredibly important observation that the eigenvectors are perpendicular or orthogonal. If there are more vectors available than dimensions, then all vectors are linearly dependent. Anyhow, if I solve that equation I get manifolds as solution, namely 4 orthogonal straight line passing through 0 (those are linear) and 2 unit circle centered at 0, orthogonal and non intersecting. The vectors shown are unit eigenvectors of the (symmetric, positive-semidefinite) covariance matrix scaled by the square root of the corresponding eigenvalue. So what I did is, I computed the eigenvalues: 1 and − 1. This solves the problem, because the eigenvalues of the matrix are the diagonal values in , and the eigenvectors are the column vectors of . The eigenvectors in X have three big problems: They are usually not orthogonal, there are not always enough eigenvectors, and Ax =λx requires A to be a square matrix. In Least squares we have equation of form. All square, symmetric matrices have real eigenvalues and eigenvectors with the same rank as . Q.E.D. Therefore the theorem is called the Eigenvectors and eigenvalues λ ∈ C is an eigenvalue of A ∈ Cn×n if X(λ) = det(λI −A) = 0 equivalent to: • there exists nonzero v ∈ Cn s.t. This means that (A I)p v = 0 for a positive integer p. If 0 q<p, then (A I)p q (A I)q v = 0: That is, (A I)qv is also a generalized eigenvector . Two eigenvectors are said to be orthogonal when they make a right angle between each other. It is easy to show A I is normal, so Lemma 3 shows that k(A I) xk= k(A I)xk= 0 is equivalent. We say that the transform ``diagonalizes'' the matrix. An \( n \times n \) matrix whose columns form an orthonormal set is called an orthogonal matrix.
