WebIn mathematics, a Hermitian matrix (or self-adjoint matrix) is a complex square matrix that is equal to its own conjugate transpose —that is, the element in the i -th row and j -th column is equal to the complex conjugate of the element in the j -th row and i -th column, for all indices i and j : Hermitian matrices can be understood as the ... WebJan 25, 2014 · A square matrix is invertible if and only if it does not have a zero eigenvalue.
