A '''Hermitian matrix''' is one that satisfies <math>M=M^\dagger</math>, where <math>M^\dagger</math> is the Hermitian conjugate of <math>M</math> (i.e., the matrix formed by transposing <math>M</math> and taking the complex conjugate of each element). As an example, the most general 2x2 Hermitian [[matrix]] has the form
