Webusing a function called the Rayleigh quotient. Definition 3.1. Let A ∈ R n×n. Then the Rayleighquotient of a nonzero vector x ∈ R is r(x) := xTAx xTx. Note that if x is an eigenvector for A with corresponding eigenvalue λ, then the Rayleigh quotient for x is r(x) = xTAx xTx = λxTx xTx = λ which is exactly the corresponding eigenvalue.
