&-- — Subtracting two MAMBO vectors or descriptions [maple]

Reference: Appendix B in Multibody Mechanics and Visualization by Harry Dankowicz, published by Springer Verlag UK, 2004.

Calling Sequence

v &-- w

&--(v,w)

Parameters

v,w: MAMBO vectors or compatible MAMBO descriptions

Description

The function &-- returns the difference between the two MAMBO vectors/descriptions v and w. It is computed using the formula

v &-- w = v &++ ((-1) &** w)

Examples

>Restart(): >DeclareTriads(a,b): >v:=MakeTranslations(a,1): >w:=MakeTranslations([a,1],[b,2]): >v &-- w;

$table ([1 = table ([Coordinates = [\begin{array}{r} 0 \\ - 1 \\ 0 \end{array}], Triad = b]), Size = 1, Type = Vector])$

>v &-- v;

$table ([Size = 0, Type = Vector])$
