VX
The VX function computes the X component of the relative translational velocity of marker I with respect to marker J resolved in the coordinate system of marker K. The time derivatives are taken in the marker L. Arguments J, K, and L are optional and default to 0, which refers to Global Frame.
Format
VX(I, J, K, L)Arguments
- I
- The marker whose velocity is to be computed.
- J
- The marker with respect to which the velocity is to be computed. The default is Global Frame.
- K
- The relative velocity vector is resolved in the coordinate system of this marker. The default is Global Frame.
- L
- Time derivatives are taken in the coordinate system of this marker. The default is Global Frame.
