WebJun 28, 2024 · 13.7: Diagonalize the Inertia Tensor. Finding the three principal axes involves diagonalizing the inertia tensor, which is the classic eigenvalue problem discussed in appendix 19.1. Solution of the eigenvalue problem for rigid-body motion corresponds to a rotation of the coordinate frame to the principal axes resulting in the matrix.

WebA matrix is positive definite if it's symmetric and all its eigenvalues are positive. The thing is, there are a lot of other equivalent ways to define a positive definite matrix. One equivalent definition can be derived using the fact that for a symmetric matrix the signs of the pivots are the signs of the eigenvalues. WebAug 28, 2016 · Repeated eigenvalues do have a connection to problems diagonalizing a matrix, though. In the case of I the solution is clear, but can we approach the case of A ′ A with repeated eigenvalues from first principles, and without having to resort to I? – Antoni Parellada Aug 28, 2016 at 14:31
