In linear algebra, a normal eigenvalue refers specifically to an eigenvalue of a normal matrix. A matrix \\( A \\) is defined as normal if it commutes with its conjugate transpose, that is: \\\[ A A^* = A^* A \\\] where \\( A^* \\) is the conjugate transpose of \\( A \\). Normal matrices include various types of matrices, such as Hermitian matrices, unitary matrices, and orthogonal matrices.
