norm

Usage

norm z

Signature

norm:

% $\to$ %

Parameter	Type	Description
z	%	a complex

Returns

Returns $z \bar z$ where $\bar z$ is the conjugate of z.

Remarks

When R is commutative, the imaginary part of $z \bar z$ is $0$, and the usual complex norm can be computed via real norm z. The imaginary part of $z \bar z$ is not necessarily $0$ when R is not commutative.
