Reparametrize the helixr→(t)=costi→+sintj→+tk→with respect to arc length measured from (1,0,0) in the direction of increasing t. 按照上面所说,可以求到答案:r→(t(s)=cos(s2)i→+sin(s2)j→+s2k→ Curvature smooth定义 unit tangent vecor:T→(t)=r′(t)|r′(t)|,可以用来描述...

Euclid (previously Euclid Core): Defines the base vector math such as points, vectors, orientations, and transforms. It also puts in place a general framework that heavily relies on interfaces which helps: identifying objects that are not meant to be modified, e.g.Tuple3DReadOnly, and simplif...

Important:There are various entities with keyvalues denoting a maximum angle as a float in the range -1.0 to 1.0, for example theFieldOfViewkeyvalue oftrigger_look. Such a keyvalue commonly refers to a dot product, which means that it isnot a linearfunction of the desired angle. A common...
Symbolic Math Toolbox™ currently does not support thedotorcrossfunctions for symbolic matrix variables and functions of typesymmatrixandsymfunmatrix. If vector calculus identities involve dot or cross products, then the toolbox displays those identities in terms of other supported functions instead....
