WY(I, J, K)

Description

The WY function computes the Y-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.

    expr2            = "VX(30301010,30301011,30301011)"

    expr3            = "VY(30301010,30301011,30301011)"

    expr4            = "VZ(30301010,30301011,30301011)"

    expr5            = "NULL"

    expr6            = "WX(30301010,30301011,30301011)"

    expr7            = "WY(30301010,30301011,30301011)"

    expr8            = "WZ(30301010,30301011,30301011)"

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.
