About

Diagonalization is a critical concept in linear algebra, allowing us to express matrices in a simpler form, making various calculations easier. A matrix is diagonalizable if it can be expressed as a product of matrices, one of which is a diagonal matrix. The Diagonalize Matrix Calculator is designed to help users quickly and easily determine if a matrix is diagonalizable, compute its eigenvalues and eigenvectors, and ultimately present the diagonal form of the matrix.

How to Use

Using the Diagonalize Matrix Calculator is straightforward. Follow these simple steps:

1. Input the Matrix: Enter the elements of the matrix in the provided fields. Ensure correctness in rows and columns.
2. Select Options: Choose options for displaying eigenvalues, eigenvectors, and other relevant output information.
3. Calculate: Click the “Diagonalize” button to process your matrix.
4. View Results: The calculator will output the diagonal form, eigenvalues, and eigenvectors of the matrix.

Formula

The general formula for diagonalization can be summarized as follows:

For a matrix A, if it can be represented as:

A = PDP^-1

Here, P is the matrix of eigenvectors, D is the diagonal matrix containing eigenvalues, and P^-1 is the inverse of the matrix of eigenvectors. The elements of the diagonal matrix D are the eigenvalues of A, represented as λ₁, λ₂, …, λ_n.

Example Calculation

Let’s consider the matrix:

A = | 4 1 |
| 2 3 |

To diagonalize this matrix:

1. Compute the characteristic polynomial: det(A – λI) = 0
2. Find the eigenvalues λ₁ = 5 and λ₂ = 2
3. Determine eigenvectors for each eigenvalue and construct P.
4. Calculate the inverse of P.
5. Finally, substitute into the diagonalization formula to get A = PDP^-1.
