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.


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.
