DeclareStates — Declaration of implicitly time-dependent variables [maple]

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

Calling Sequence

DeclareStates(q1, ..., qn)

Parameters

q1, ..., qn: names

Description

The function DeclareStates establishes the names q1, ..., qn as implicitly time-dependent variables.

The function DeclareStates results in permanent changes to the global variables GlobalExplicit and GlobalImplicit.

Examples

>Restart(): >DeclareStates(q1,q2,u1): >print(GlobalExplicit);

$\{q1 = q1 (t), q1t = \frac{ⅆ}{ⅆ t} q1 (t), q2 = q2 (t), q2t = \frac{ⅆ}{ⅆ t} q2 (t), u1 = u1 (t), u1t = \frac{ⅆ}{ⅆ t} u1 (t)\}$

>print(GlobalImplicit);

$\{q1 (t) = q1, q2 (t) = q2, u1 (t) = u1, \frac{ⅆ}{ⅆ t} q1 (t) = q1t, \frac{ⅆ}{ⅆ t} q2 (t) = q2t, \frac{ⅆ}{ⅆ t} u1 (t) = u1t\}$
