Linear Algebra & Matrices

Eigenvalue & Eigenvector Calculator

Find eigenpairs for real symmetric matrices or general real 2 × 2 matrices.

Linear Algebra & Matrices

Enter matrix values

Exact structural results; labelled numerical approximations where required
Matrix A

Use signed finite decimals. Fill every visible cell. Fractions, commas, and scientific notation are not accepted.

Linear algebra result

Enter valid values to see the result.

Your entries are calculated in this browser and are not submitted to 365CALCS.COM.

Quick guide

How to use this calculator

  1. Set the matrix dimensions required by the task.
  2. Fill every visible entry and any operation-specific control.
  3. Read the result type, factors, classification, and disclosed limitations.

Calculation method

Apply the stated linear-algebra contract

Av = λv

Undefined, singular, dimensionally incompatible, dependent, or unsupported inputs receive an explicit message instead of a fabricated numeric result.

Worked example

Example interpretation

Symmetric matrices have a real orthonormal eigenbasis.

Av = λv

Supported inputs

Precision and limits

Matrix size

Input matrices are limited to 1–6 rows and columns; operation-specific square, rank, or compatibility rules still apply.

Entry precision

Enter signed finite decimals with at most 30 digits and 15 decimal places.

Numerical policy

Results use real double-precision arithmetic, a 1e-10 structural tolerance where stated, bounded iterations, and labelled approximations.

Supported scope

Larger nonsymmetric matrices and complex eigenvectors are outside this bounded browser contract.
