WebEssential vocabulary words: eigenvector, eigenvalue. In this section, we define eigenvalues and eigenvectors. These form the most important facet of the structure theory of square matrices. As such, eigenvalues and eigenvectors tend to play a key role in the real-life applications of linear algebra. Subsection 5.1.1 Eigenvalues and Eigenvectors WebAn eigenvane, as it were. The definition of an eigenvector, therefore, is a vector that responds to a matrix as though that matrix were a scalar coefficient. In this equation, A is the matrix, x the vector, and lambda the …
