It is not necessary to test if the matrix is symmetric but I need to use this decomposition and it works only if Mathematica feels one hermitian matrix (also positive) – Raffaele Carlone May 14 '12 at 7:37... A matrix is Hermitian if it equals its own conjugate transpose. In other words, if you flip it across its top-left to bottom-right diagonal and negate the second element of all the two-element leaf-lists, it is identical to the input matrix. Note that the order of flipping and negating is …

Hermitian Matrices It is simpler to begin with matrices with complex numbers. Let x= a+ ib, where a;bare real numbers, and i= p 1. Then, x = a ibis the complex conjugate of x. In the discussion below, all matrices and numbers are complex-valued unless stated otherwise. Let Mbe an n nsquare matrix with complex entries. Then, is an eigenvalue of Mif there is a non-zero vector ~vsuch that M~v= ~v... The wording of the problem implies that H is hermitian and that U must therefore be a unitary matrix given by U = e^(i*H)

VECTOR NORMS AND MATRIX NORMS Some work is required to show the triangle inequality for the p-norm. Proposition 4.1. If E is a ?nite-dimensional vector space over R or C, for every real number p ? 1, the p-norm is indeed a norm. The proof uses the following facts: If q ? 1isgivenby 1 p + 1 q =1, then (1) For all ?,? ? R,if?,? ? 0, then ?? ? ?p p + ?q q. (?) (2... 8.5 UNITARY AND HERMITIAN MATRICES Problems involving diagonalization of complex matrices, and the associated eigenvalue problems, require the concept of unitary and Hermitianmatrices. These matrices roughly correspond to orthogonal and symmetric real matrices. In order to define unitary and Hermitian matrices, we first introduce the concept of the conjugate transposeof a com-plex matrix. …

## How To Show A Matrix Is Hermitian

### Hermitian matrix and unitary matrix are the counterparts of symmetric and orthogonal matrix in R, the following theorems in Rcan be readily transformed to the corresponding forms in Cby substituting the transpose by conjugate transpose and orthogonal matrix by unitary matrix.
