Authors: enable JavaScript in your browser. Noté /5. The first notation, a vinculum, avoids confusion with the notation for the conjugate transpose of a matrix, which can be thought of as a generalization of the complex conjugate. (gross), © 2020 Springer Nature Switzerland AG. The complex conjugate transpose of a matrix interchanges the row and column index for each element, reflecting the elements across the main diagonal. The notation A^* is sometimes also used, which can lead to confusion since this symbol is also used to denote the conjugate transpose. by Marco Taboga, PhD.

Achetez neuf ou d'occasion In addition, the new concept of conjugate product for complex polynomial matrices is also proposed in order to establish a unified approach for solving a type of complex matrix equation. For example, the solvability of a real Sylvester matrix equation can be characterized by matrix similarity; however, the solvability of the con-Sylvester matrix equation in complex conjugate form is related to the concept of con-similarity. For example, if B = A' and A(1,2) is 1+1i, then the element B(2,1) is 1-1i. The result of the sequential application of these two operations is called conjugate transpose (or Hermitian transpose). When b=0, z is real, when a=0, we say that z is pure imaginary. For example, if B = A' and A (1,2) is 1+1i , then the element B (2,1) is 1-1i. Part of Springer Nature.
