WebThis results in a method that is able to do the classification based on the eigenvectors that belong to the largest eigenvalues of the covariance matrix of both Quadtree nodes. Both eigenvectors are compared to each other by applying a threshold ϵ on the angle that is specified between the eigenvectors and the x-axis. WebUnlike nontensor approaches, the dimensionality in the tensor approach can be eliminated. Thus, EDS is defined as the ratio of the Euclidean distance (d S, S ′) between the measured and predicted stress tensors to the Euclidean distance (d S, O) between the measured stress tensor and origin (in a two-dimensional (2D) space as shown in Fig. 2): (9) EDS S, S ′ = d S, …

In that case it can be proved (see below) that1 (i) the eigenvalues are real (ii) the three eigenvectors form an orthonormal basis nˆ i . Webwhich represents a proper counterclockwise rotation by an angle θ in the x–y plane. Consider the eigenvalue problem, R(θ)~v = λ~v . (2) Since R(θ) rotates the vector ~v by an angle θ, we conclude that for θ 6= 0 (mod π), there are no real eigenvectors ~vthat are solutions to eq. (2).
