Finding eigenvector of 3x3 matrix

WebApr 5, 2024 · You can easily find the eigenvector for a given matrix using an eigen vector calculator because it contains simple steps. These steps are: In the first step, enter the value of the number of rows and columns in the respective boxes. Now enter all values of all entries of the matrix. You can also use the random option to select a random matrix. WebTo find the eigenvalues of A, solve the characteristic equation A - λI = 0 (equation (2)) for λ and all such values of λ would give the eigenvalues. To find the eigenvectors of A, substitute each eigenvalue (i.e., the value of λ) in equation (1) (A - λI) v = O and solve for v using the method of your choice.
