### What is Meant by Eigenvalue?

In Mathematics, an Eigenvalue is a scalar value that is associated with the system of linear equations (also called matrix equations). The eigenvalue is also known as the latent roots or characteristic root or characteristic value or the proper value. It is associated with the eigenvectors. The eigenvalues are used in the analysis of linear transformations. The basic equation to represent the eigenvalue is given as AX = λX, Here λ is a scalar value which is the eigenvalue of the matrix A.
