YAW
The YAW function computes the first angle, in radians, of a body-3 Yaw-Pitch-Roll rotation sequence.
Format
YAW(I, J)Description
- First, rotate in a counterclockwise direction about the z-axis of the I coordinate system [YAW].
- Second, rotate counterclockwise about the negative y-axis of the I coordinate system [PITCH].
- Third, rotate counterclockwise about the x-axis of the I coordinate system [ROLL].
The first argument, marker I, must be specified. The second argument, marker J, is optional.
Arguments
- I
- The marker whose rotational displacement is to be computed.
- J
- The marker with respect to which the rotational displacement is to be computed. If omitted, it defaults to the ground coordinate system.
