WZ(I, J, K)

Description

The WZ function computes the Z-component of the relative rotational velocity of marker I with respect to marker J, as resolved in the coordinate system of marker K. The first argument, marker I, must be specified.  The second and third arguments, markers J and K, are optional.

Arguments

I

The marker whose velocity is to be computed.

J

The marker with respect to which the velocity is to be computed.  This argument is optional. If omitted, it defaults to the ground coordinate system.

K

The resultant velocity vector is resolved in the coordinate system of the K marker.  This argument is optional.  If omitted, it defaults to the ground coordinate system.
