geom3d

 coordinates
 compute the coordinates of a given point

 Calling Sequence coordinates(P)

Parameters

 P - a point

Description

 • The routine returns the coordinates of the given point P.
 • The output will be represented as a list of three elements denoting the x''-coordinate, y''-coordinate, and z''-coordinate respectively.
 • The command with(geom3d,coordinates) allows the use of the abbreviated form of this command.

Examples

 > $\mathrm{with}\left(\mathrm{geom3d}\right):$
 > $\mathrm{point}\left(A,2,8,-1\right),\mathrm{point}\left(M,u,v,z\right)$
 ${A}{,}{M}$ (1)
 > $\mathrm{coordinates}\left(A\right)$
 $\left[{2}{,}{8}{,}{-}{1}\right]$ (2)
 > $\mathrm{coordinates}\left(M\right)$
 $\left[{u}{,}{v}{,}{z}\right]$ (3)
