The conj( Command

conj(*z*) returns the complex conjugate of the complex number z. If z is represented as x+iy where x and y are both real, conj(*z*) returns x-iy. Also works on a list of complex numbers.

conj(3+4i)
     3-4i

The conjugate of a number \(z\) is often written \(\overline{z}\), and is useful because it has the property that \(z\overline{z}\) and \(z+\overline{z}\) are real numbers.
