WebThe eigenvector is a vector that is associated with a set of linear equations. The eigenvector of a matrix is also known as a latent vector, proper vector, or characteristic … WebAn identity matrix has only one eigenvalue which is 1. The eigenvalues of triangular matrices and diagonal matrices are nothing but the elements of their principal diagonal. The sum of eigenvalues of matrix A is equal to the sum of its diagonal elements. The product of eigenvalues of matrix A is equal to its determinant.
