&** — Scalar multiplication of a MAMBO vector or description [maple]

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

Calling Sequence

k &** w

&**(k,w)

Parameters

k: algebraic expression

w: MAMBO vector or description

Description

The function &** returns the scalar multiplication of an algebraic expression k with a vector or description v.

To ensure proper evaluation order, it is recommended to enclose the algebraic expression within parentheses.

Examples

>Restart():
>DeclareTriads(a):
>v:=MakeTranslations(a,1,2,3):
>2 &** v;

$table ([1 = table ([Coordinates = [\begin{array}{r} 2 \\ 4 \\ 6 \end{array}], Triad = a]), Size = 1, Type = Vector])$

>(-1/VectorLength(v)) &** v;

$table ([1 = table ([Coordinates = [\begin{array}{c} - \frac{1}{14} \sqrt{14} \\ - \frac{1}{7} \sqrt{14} \\ - \frac{3}{14} \sqrt{14} \end{array}], Triad = a]), Size = 1, Type = Vector])$
