Hermitian adjoint matrix, of a given (rectangular or square) matrix over the field of complex numbers

The matrix whose entries are the complex conjugates of the entries of , i.e. . Thus, the adjoint matrix coincides with its complex-conjugate transpose: where denotes complex conjugation and the denotes transposition.

Properties of adjoint matrices are:

Adjoint matrices correspond to adjoint linear transformations of unitary spaces with respect to orthonormal bases.
