WM

The WM function returns the magnitude of the angular velocity vector of marker i with respect to marker j. Marker j defaults to the global coordinate system if it is not specified.

Format

WM(i[,j])

Arguments

i	The marker whose velocity is being measured.
j	The marker with respect to which the velocity is being measured. Set j = 0, while still specifying l, if you want j to default to the global coordinate system.

Extended Definition

Mathematically, WM is calculated as follows:

where:  

•	is the angular velocity vector of marker i in ground.

•	is the angular velocity vector of marker j in ground.

Examples

MARKER/1236, QP=4,6,7 EU=90D,90D,90D, PART=23
MARKER/2169, PART=16
REQUEST/16
,F1=WM(1236,2169)/
,F2=WX(1236,2169,2169)/
,F3=WY(1236,2169,2169)/
,F4=WZ(1236,2169,2169)

In its first column, REQUEST/16 contains the magnitude of the angular velocity vector of Marker 1236 and Marker 2169.
