    SIFAT-SIFAT KESETARAAN PADA MATRIKS SECONDARY NORMAL
    (2014-03-25) Nursyahlina, Nursyahlina; Gemawati, S.; Sirait, Asli
    A square matrix A is called a secondary normal matrix if AAθ = Aθ A, where Aθ is a secondary conjugate transpose of the matrix A, which is different from the conjugate transpose matrix. In this paper, we discuss some equivalent conditions of a secondary normal matrix that is if A is a secondary normal matrix then it exists a secondary unitary matrix P obtained by diagonalization and Gram-Schmidt process, such that Pθ A P = D, where D is a diagonal matrix. More over if A = VP and V is a secondary uniter matrix then A is a secondary normal matrix.
