New Normal Matrices and the Unitary Decomposition on the Tensor Sum
By using the concept of normal matrix,and the theory of singular value decomposition,some properties of a class of matrix A which satisfies A*=kA2(0≠k ∈ R)were explored.Results show that it is a normal matrix and the singular value decomposition of A was obtained.A formula(A⊕B)*=A*⊕B* and the unitary decomposition of the tensor sum of such two matrices was investigated as well aided by tensor product of matrices,expanding the fundamental theory of the normal matrix.
