The system matrix has 23 negative eigenvalues

Webmatrix Sas above now leads to the system _y= A 3ywhere A 3 is the matrix of Example 8.2.1 above. Finally, in the case of a complex conjugate pair of eigenvalues we in-troduce the column vectors and of x8.2.2 and form the matrix Sfrom these. Transforming again via x = Sy we get the equations (8.6) with y 1 = a;y 2 = b. WebSep 17, 2024 · A is a product of a rotation matrix (cosθ − sinθ sinθ cosθ) with a scaling matrix (r 0 0 r). The scaling factor r is r = √ det (A) = √a2 + b2. The rotation angle θ is the counterclockwise angle from the positive x -axis to the vector (a b): Figure 5.5.1. The eigenvalues of A are λ = a ± bi.
