# ACCZ

The ACCZ function computes the Z-component of the relative translational acceleration of marker I with respect to marker J, as resolved in the coordinate system of marker K.

ACCZ(I, J, K, L)

## Description

The time derivatives are taken in the marker L frame.

## Arguments

I
The marker whose acceleration is to be computed. Must be specified.
J
The marker with respect to which the acceleration is to be computed. This argument is optional. If omitted, it defaults to the ground coordinate system.
K
The resultant acceleration vector is resolved in the coordinate system of the K marker. This argument is optional. If omitted, it defaults to the ground coordinate system.
L
Time derivatives are taken in the coordinate system of this marker. This argument is optional. If omitted, it defaults to the ground coordinate system.
