Types of Eigenvector

The eigenvectors calculated for the square matrix are of two types which are,

  • Right Eigenvector
  • Left Eigenvector

Right Eigenvector

The eigenvector which is multiplied by the given square matrix from the right-hand side is called the right eigenvector. It is calculated by using the following equation,

AVR = λVR

Where,

  • A is given square matrix of order n×n,
  • λ is one of the eigenvalues, and
  • VR is the column vector matrix

The value of VR is,

[Tex]\bold{V_{R} = \begin{bmatrix} v_{1}\\ v_{2}\\ v_{3}\\ .\\ .\\ v_{n}\\ \end{bmatrix}}[/Tex]

Left Eigenvector

The eigenvector which is multiplied by the given square matrix from the left-hand side is called the left eigenvector. It is calculated by using the following equation,

VLA = VLλ

Where,

  • A is given square matrix of order n×n,
  • λ is one of the eigenvalues, and
  • VL is the row vector matrix.

The value of VL is,

VL = [v1, v2, v3,…, vn]

Eigenvalues

Eigenvalues and Eigenvectors are the scalar and vector quantities associated with Matrix used for linear transformation. The vector that does not change even after applying transformations is called the Eigenvector and the scalar value attached to Eigenvectors is called Eigenvalues. Eigenvectors are the vectors that are associated with a set of linear equations. For a matrix, eigenvectors are also called characteristic vectors, and we can find the eigenvector of only square matrices. Eigenvectors are very useful in solving various problems of matrices and differential equations.

In this article, we will learn about eigenvalues, eigenvectors for matrices, and others with examples.

What are Eigenvalues?

Eigenvalues are the scalar values associated with the eigenvectors in linear transformation. The word ‘Eigen’ is of German Origin which means ‘characteristic’. Hence, these are the characteristic value that indicates the factor by which eigenvectors are stretched in their direction. It doesn’t involve the change in the direction of the vector except when the eigenvalue is negative. When the eigenvalue is negative the direction is just reversed. The equation for eigenvalue is given by...
