MATRIX("HERMITIAN",order)

• $order$ 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 A=A^T, where A^T denotes the conjugate transpose, which is equivalent to the condition a_(ij)=a^__(ji).
• A hermetian matrix is also called as self-adjoint matrix.
• The following matrix is the example of 3x3 Hermitian matrix:

${\begin{bmatrix}2&2+i&4\\2-i&3&i\\4&-i&1\\\end{bmatrix}}$.

• 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.
