How to check if a matrix is hermitian
Web21 apr. 2016 · Transpose for real matrices is equivalent to Hermitian (complex conjugate transpose) for complex matrices. Therefore, you can use the same matlab operator to generate the Hermitian for a complex matrix. For example: Theme. Copy. x = [1+j; 1-j; 2-j; 1+2j] % random complex matrix. x =. 1.0000 + 1.0000i. 1.0000 - 1.0000i. WebThe matrix is Hermitian and has a real-valued diagonal. Test whether the matrix is symmetric. tf = issymmetric (A) tf = logical 0 The result is logical 0 ( false) because A is not symmetric. In this case, A is equal to its complex conjugate transpose, A', but not its nonconjugate transpose, A.'. Change the element in A (3,1) to be 1i. A (3,1) = 1i;
