Repeated eigenvalues.

Description
"In this video lecture the Eigenvalues and coefficients are defined and explained with example.Complex eigenvalues are discussed and the application of Complex eigenvalues are shown through solving problems. Repeated eigenvalues are also described on this context. A matrix with a repeated eigenvalue but only one lineful of
eigenvectors is called defective. A matrix can have a repeated
eigenvalue and not be defective. Every solution is a normal mode. This is called the complete case.
