A … WebRayleigh quotient. In mathematics, the Rayleigh quotient [1] ( / ˈreɪ.li /) for a given complex Hermitian matrix M and nonzero vector x is defined as: [2] [3] For real matrices and vectors, the condition of being Hermitian reduces to that of being symmetric, and the conjugate transpose to the usual transpose .
