Student[VectorCalculus][MapToBasis] - convert a Vector or vector field to a different coordinate system
Calling Sequence
MapToBasis(V, c)
Parameters
V
-
Vector or Vector-valued procedure; specify the Vector or vector field
c
(optional) name or name[name, name, ...]; specify the new coordinate system
Description
The MapToBasis(V, c) calling sequence converts the Vector or vector field V to the coordinate system c.
If V is a Vector-valued procedure, it is interpreted as a vector field.
If c is not specified, the current default coordinate system is used as the new coordinate system.
If c is specified and V represents a vector field, the new coordinate system must be indexed with the names of the new coordinates. Otherwise, an error is raised. If V represents a Vector, no coordinate names are required.
If a coordinate system attribute is specified on V, V is interpreted in this coordinate system.
If a coordinate system attribute is not specified on V, V is interpreted as a Vector or vector field in the current default coordinate system. If the default coordinate system is not compatible with the new coordinate system, an error is raised.
Examples
When transforming vector fields, you must specify coordinate names for the new coordinate system.
