Eigenvalues Calculator
Find eigenvalues and eigenvectors for small square matrices.
Eigenvalues
λ = 1
Eigenvectors
1: [1, 0], [0, 1]
Status
Repeated real eigenvalue.
Eigenpairs
Eigenvalues from the characteristic polynomial.
| Eigenvalue | Eigenvector |
|---|---|
| 1 | [1, 0], [0, 1] |
Formula
Eigenvalues come from the characteristic polynomial. It solves 1x1 and 2x2 matrices exactly and shows a real eigenvector for each supported eigenvalue.
Use the eigenvalues calculator to enter a small square matrix and inspect the eigenpairs it produces. It supports 1x1 and 2x2 matrices and reports a clear message when the matrix is too large or has complex roots.
