ACCM (I, J, L)

Description

The ACCM function computes the magnitude of the total relative translational acceleration between markers I and J. Time derivatives are calculated in the reference frame of marker L. The first argument, marker I, must be specified.  The second and third arguments are optional.

Arguments

I

The marker whose acceleration is to be computed.

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.

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.
