SchurDecomposition
  • SchurDecomposition[ m ] yields the Schur decomposition for a numerical matrix m. The result is a list q , t where q is an orthogonal matrix and t is a block upper triangular matrix.
  • The original matrix m is equal to q . t . Conjugate[Transpose[ q ]].
  • SchurDecomposition[ m , Pivoting -> True] yields a list q , t , d where d is a permuted diagonal matrix such that m . d is equal to d . q . t . Conjugate[Transpose[ q ]].
