HERMITIAN HERMITIAN Matrix Hermitian (Conjugate Transpose) Operator Usage Computes the Hermitian of the argument (a 2D matrix). The syntax for its use is y = a'; where a is a M x N numerical matrix. The output y is a numerical matrix of the same type of size N x M. This operator is the conjugating transpose, which is different from the transpose operator .' (which does not conjugate complex values).
