Copy

public void Ln()

Public Sub Ln

public:
void Ln()

member Ln : unit -> unit

Exceptions

Exception	Condition
MathematicsException	The quaternion is not a unit quaternion.

Remarks

Important: This method requires that the quaternion is a unit quaternion.

The natural logarithm of a quaternion q is defines as:

ln(q) = ln(cos(θ) + usin(θ)) = ln(e^uθ) = uθ

The result is returned as a quaternion with the form: (0, uθ)
