Rayleigh inequality
In mathematics, the Rayleigh quotient for a given complex Hermitian matrix M and nonzero vector x is defined as: For real matrices and vectors, the condition of being Hermitian reduces to that of being symmetric, and the conjugate transpose $${\displaystyle x^{*}}$$ to the usual transpose See more An empirical covariance matrix $${\displaystyle M}$$ can be represented as the product $${\displaystyle A'A}$$ of the data matrix $${\displaystyle A}$$ pre-multiplied by its transpose $${\displaystyle A'}$$. … See more • Field of values • Min-max theorem • Rayleigh's quotient in vibrations analysis • Dirichlet eigenvalue See more Sturm–Liouville theory concerns the action of the linear operator This is sometimes presented in an equivalent form, obtained by separating the integral in the … See more 1.
