ishermitian

Computes if matrix is hermitian or skew-hermitian.

Syntax

• res = ishermitian(x)
• res = ishermitian(x, 'skew')
• res = ishermitian(x, 'nonskew')

Input argument

• x - a numeric value: scalar or matrix (double or single, integers, logical).

Output argument

• res - a logical.

Description

ishermitian(x) computes if matrix is hermitian or skew-hermitian.

A matrix is skew-hermitian if the complex conjugate transpose of the matrix is equal to the negative of the original matrix.

Example

ishermitian([1 0 1i; 0 1 0; -1i 0 1])
