Determinant of hermitian matrix

WebDeterminant of any matrix = multiplication of eigen values of the matrix The eigen values of Hermitian matrix are real. Determinant of Hermitian matrix = Multiplication of Eigen Values of Hermitian matrix= real So the determinant of Hermitian matrix is real. 2 Sponsored by The Penny Hoarder WebHermitian or real symmetric matrices are easy to understand: both classes are real vector spaces (a linear combination of Hermitian matrices with real coefficients is Hermitian, and same for real symmetric matrices). Unitary (or orthogonal) matrices are more difficult. Example: describe all 2 ×2 unitary matrices with determinant 1. Let our ...
