About Characteristic Polynomial Calculator
We provide a fast, private way to compute p(λ) for small square matrices without installing software.
Characteristic Polynomial Calculator helps you check homework, lecture examples, and engineering linear algebra steps. All computation runs locally in your browser.
The site includes guides on definitions, formulas, worked examples, and blog articles that go deeper into eigenvalues and matrix theory.
We aim for clear notation, accessible contrast, and mobile-friendly layouts so you can work from a phone or laptop.
- Browser-only matrix input and symbolic determinant expansion
- Choice of det(A − λI) or det(λI − A)
- Educational articles linked from the home page and blog
