CQuaternion

public CQuaternion()

CQuaternion

public CQuaternion(RealNum real,
                   RealNum imag,
                   RealNum jmag,
                   RealNum kmag)

Method Detail

re

public RealNum re()

Description copied from class: Quantity

The value of the real component, as a RealNum. The unit() is not factored in, so you actually need to multiply by unit() to get the true real component.

Overrides:

re in class Quantity

im

public RealNum im()

Description copied from class: Quantity

The value of the imaginary component, as a RealNum. The unit() is not factored in, so you actually need to multiply by unit() to get the true imaginary component.

Overrides:

im in class Quantity

jm

public RealNum jm()

Description copied from class: Quantity

The value of the "j" component, as a RealNum. The unit() is not factored in, so you actually need to multiply by unit() to get the true "j" component.

Overrides:

jm in class Quantity

km

public RealNum km()

Description copied from class: Quantity

The value of the "k" component, as a RealNum. The unit() is not factored in, so you actually need to multiply by unit() to get the true "k" component.

Overrides:

km in class Quantity

writeExternal

public void writeExternal(ObjectOutput out)
                   throws IOException

Specified by:
