Matrix Eigenvalues and Eigenvectors

Enter the values of a 4×4 matrix below (you can also input a smaller n×n sub-matrix by filling in just the top-left n rows and n columns), then select a method to compute its eigenvalues and eigenvectors.

By default there are 16 entries (4×4). If you want a smaller matrix, just fill in the top-left n×n block (e.g. 2×2 or 3×3).
Click "Calculate (Exact)" to see the real eigenvalues and corresponding eigenvectors.
Or switch to the Power Iteration tab for an approximate dominant eigenpair.
Click "Clear" to reset all inputs.
Complex eigenvalues are not displayed here.
