Also, the values can be anything since no restrictions were specified. A square complex matrix whose transpose is equal to the matrix with every entry replaced by its complex conjugate (denoted here with an overline) is called a self-adjoint matrix or a Hermitian matrix (equivalent to the matrix being equal to its conjugate transpose ); that is, A is self-adjoint or Hermitian if A = A . That is, D is diagonal if and only if it is square and dij = 0 for i j. Find its determinant, adjunct matrix, B^{\frac{1}{2}} and B^3 . 1991. "SquareMatrixQ."
