For a matrix A whose entries are complex numbers, the complex conjugate of the transpose
Chapter 5, Problem 5.5A.6(choose chapter or problem)
For a matrix A whose entries are complex numbers, the complex conjugate of the transpose is denoted by AH. For matrices in which AH = A (called Hermitian): (a) Prove that the eigenvalues are real. (b) Prove that eigenvectors corresponding to different eigenvalues are orthogonal (in the sense that i m= 0, where denotes the complex conjugate).
