ConvertVector

  

converts Cartesian free Vectors, rooted Vectors and position Vectors among themselves

 

Calling Sequence

Parameters

Description

Examples

Calling Sequence

ConvertVector(v,form)

ConvertVector(v,form, root )

Parameters

v

-

'Vector'(algebraic); the Cartesian free Vector, rooted Vector or position Vector to convert

form

-

name; specify the type of Vector to be converted to: free, rooted or position

root

-

(optional) list(algebraic) or Vector(algebraic); root point of the converted Vector

Description

• 

The ConvertVector command converts Cartesian free Vectors, rooted Vectors and position Vectors among themselves by specifying the desired type. If v is not a Cartesian Vector, an error is raised.

• 

If form is rooted, the root point can be specified as a list or a free Vector with the extra optional parameter root. If root is a list, it is interpreted in Cartesian coordinates, if it is a free Vector in non-Cartesian coordinates, an appropriate transformation is made to obtain a Cartesian root.

– 

If form is rooted, v is a free, rooted or position Vector and root is provided, the result is the Vector rooted at root.

– 

If form is rooted, v is a position Vector and root is not provided, then the Vector is rooted at the Cartesian origin.

– 

If form is rooted, v is a free Vector and root is not provided, an error is raised.

• 

The Student[VectorCalculus] package uses the same Vector data structures as the VectorCalculus package. For details about the various types of Vectors in these packages, see VectorCalculus,Details.
