MATRIX("HERMITIAN",order)


  • is the order of the Hermitian matrix.

Description

  • This function gives the Hermitian matrix of order 3.
  • A Hermitian matrix is defined as the square matrix with complex entries which is equal to its own conjugate transpose.
  • i.e., the matrix A is Hermitian if and only if , where denotes the conjugate transpose, which is equivalent to the condition .
  • A hermetian matrix is also called as self-adjoint matrix.
  • The following matrix is the example of 3x3 Hermitian matrix:

.

  • The diagonal elements must be real, as they must be their own complex conjugate.
  • An integer or real matrix is Hermitian iff it is symmetric.
  • In calci, users can change the order and number of the Hermitian matrices.

Examples
