Normal. Every Hermitian matrix is a normal matrix. That is to say, =. Proof =, so = =. Diagonalizable. The finite-dimensional spectral theorem says that any Hermitian matrix can be diagonalized by a unitary matrix, and that the resulting diagonal matrix has only ... Zobacz więcej In mathematics, a Hermitian matrix (or self-adjoint matrix) is a complex square matrix that is equal to its own conjugate transpose—that is, the element in the i-th row and j-th column is equal to the complex conjugate of … Zobacz więcej Additional facts related to Hermitian matrices include: • The sum of a square matrix and its conjugate transpose $${\displaystyle \left(A+A^{\mathsf {H}}\right)}$$ is Hermitian. • The difference of a square matrix and its … Zobacz więcej • Complex symmetric matrix – Matrix equal to its transpose • Haynsworth inertia additivity formula – Counts positive, negative, and zero eigenvalues of a block partitioned Hermitian matrix • Hermitian form – Generalization of a bilinear form Zobacz więcej Hermitian matrices are fundamental to quantum mechanics because they describe operators with necessarily real eigenvalues. … Zobacz więcej Main diagonal values are real The entries on the main diagonal (top left to bottom right) of any Hermitian matrix are real. Only the main diagonal entries are necessarily real; Hermitian matrices can have arbitrary … Zobacz więcej In mathematics, for a given complex Hermitian matrix M and nonzero vector x, the Rayleigh quotient $${\displaystyle R(M,\mathbf {x} ),}$$ is defined as: For real matrices and vectors, the condition of being Hermitian reduces to that of being … Zobacz więcej • "Hermitian matrix", Encyclopedia of Mathematics, EMS Press, 2001 [1994] • Visualizing Hermitian Matrix as An Ellipse with Dr. Geo, by Chao-Kuei Hung from Chaoyang University, gives a more geometric explanation.
