Eigenvalue calculator

Find eigenvalues of supported square matrices, with exact or approximate output depending on the problem.

How to use this calculator

Edit the square matrix after eigs⁡\operatorname{eigs}. Its diagonal entries are the eigenvalues in this starter example.

Tap the math below to edit it and see the result. Once a result is ready, press Tab on a hardware keyboard to accept it. Outside a matrix, Return completes the line; the phone math keyboard has the same Return action.

What to know

Larger or difficult matrices may yield numerical approximations or reach the time limit.

Mathlean combines visual mathematical input with computation and canvas tools. Results depend on the expression and available engine support; check important answers independently.
