WebEigenvalues and eigenvectors prove enormously useful in linear mapping. Let's take an example: suppose you want to change the perspective of a painting. If you scale the x direction to a different value than the y direction (say x -> 3x while y -> 2y), you simulate a change of perspective. This would represent what happens if you look a a scene ... WebOct 13, 2024 · $\begingroup$ Actually it's clearly harder to diagonalize a 3x3 symmetric matrix (giving its 3 real eigenvalues) than it is to find the determinant (product of the eigenvalues). The latter is a polynomial of matrix coefficients while orthogonal $\Gamma$ cannot be expressed so simply. $\endgroup$
