WebEigenvector and eigenvalue: de nition Let M be any d d matrix. M de nes a linear function, x 7!Mx. This maps Rd to Rd. We say u 2Rd is an eigenvector of M if Mu = u for some scaling constant . This is the eigenvalue associated with u. Key point: M maps eigenvector u onto the same direction. WebSuppose . Then is an eigenvector for A corresponding to the eigenvalue of as. In fact, by direct computation, any vector of the form is an eigenvector for A corresponding to . We …

Webeigenvectors: x = Ax De nitions A nonzero vector x is an eigenvector if there is a number such that Ax = x: The scalar value is called the eigenvalue. Note that it is always true that A0 = 0 for any . This is why we make the distinction than an eigenvector must be a nonzero vector, and an eigenvalue must correspond to a nonzero vector.
