 GetRootPoint
 return the root point of rooted Vector

 Calling Sequence GetRootPoint(v)

Parameters

 v - Vector; a rooted Vector

Description

 • The call GetRootPoint(v) returns the root point, as a free Vector, of the vector space to which the rooted Vector v belongs.
 • For more information about Vectors in the VectorCalculus package, see VectorCalculus,Details.

Examples

 > with(VectorCalculus):
 > vs := VectorSpace(cartesian[x,y], [a,b]):
 > v := vs:-Vector([c,d]):
 > GetRootPoint(v);
 $\left({a}\right){{e}}_{{x}}{+}\left({b}\right){{e}}_{{y}}$ (1)
