Inner product of complex numbrs

  1. Oct 27, 2012 #1
    I would like if someone could either verify or clarify my thinking about inner products.

    There is a matrix, V that is m x n, that is made up of complex numbers. When matrix V is multiplied by its hermitian then the product is a matrix with the same integer down the main diagonal (i.e. Eigenvalues are all the same).

    If you mean by its Hermitian the conjugate transpose. There are matrices that are self adjoined, and don't change under that operation. When you multiply such a matrix by its conjugate transpose the eigenvalues are squared.

    What do you mean by self adjoining?

    The definition of a self adjoint or Hermitian matrix is, that the matrix is the same after mirroring on the main diagonal and complex conjugation. What you mean by Hermitian of a matrix I don't know.
