Physics Vector Module: Subtract two points to get a vector?

[jj20...@gmail.com]

Is it possibly to subtract two points in the same reference frame and get the relative position vector connecting the two?

[Aaron Meurer]

What SymPy submodule are you using? There is more than one that has
the notion of point of vector.

I'm using sympy.physics.mechanics. It seems to use physics.vector.

Sorry I haven't answered in a week. I hadn't set the mail fowarding settings right.

You can get the relative position vector by "pos_from" method in Point class. Here are the docs http://docs.sympy.org/latest/modules/physics/vector/api/kinematics.html#sympy.physics.vector.point.Point.pos_from
