DZ(I, J, K)

Description

The DZ function computes the Z-component of the relative translational displacement 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, whereas the second and third arguments, markers J and K, are optional.

Example

    comment             = "bush-disp"

    id                  = "70000040"

    type                = "EXPRESSION"

    expr1               = "NULL"

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

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

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

    expr5               = "NULL"

    expr6               = "NULL"

    expr7               = "NULL"

    expr8               = "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.
