AttitudeConvert(Variable, Variable, Spacecraft, Array) Function

Description

Converts the from3Vector from the fromAttitude reference system to the toAttitude reference system, using referenceSpacecraft as the reference Spacecraft.

This overload should only be used to convert position vectors. To convert a velocity, be sure to use the overload that allows you to specify the conversion type as an additional argument.

Timing Precision Mode

This page describes functionality in millisecond timing precision mode.

referenceSpacecraft
Description:	The Spacecraft object to which the attitude frames are referenced.

from3Vector
Description:	A three-element array containing the position vector in the input attitude system.
Required Size:	At least 3

Return Value

Type:

Array of number (size = 3)

Returns a three-element array containing the converted vector in the output attitude system.
