For the modulus and phase functions ${M}_{\nu}\left(x\right)$, ${\theta}_{\nu}\left(x\right)$, ${N}_{\nu}\left(x\right)$, and ${\varphi}_{\nu}\left(x\right)$ see §10.18.

In the graphics shown in this subsection, height corresponds to the absolute value of the function and color to the phase. See also p. About Color Map.

For the notation see §10.24.
