DX(I, J, K)

Description

The DX function computes the X-component of the relative translational displacement of marker Iwith 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.

Example

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

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

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

    expr5               = "NULL"

Arguments

I

The marker whose displacement is to be computed.

J

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

K

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