Shortcut to find eigenvalues of 3x3 matrix
SpletTo find the eigenvalues of a 3×3 matrix, X, you need to: First, subtract λ from the main diagonal of X to get X – λI. Now, write the determinant of the square matrix, which is X – λI. Then, solve the equation, which is the det (X – λI) = 0, for λ. The solutions of the eigenvalue equation are the eigenvalues of X. SpletFinding the determinant of a matrix larger than 3x3 can get really messy really fast. There are many ways of computing the determinant. One way is to expand using minors and …
