ChangeFrame(M)

Create a few manifolds:

Example 1.

Change to the frame M, check the name of the current frame and obtain the default basis for the tangent space of the current frame.

Example 2.

Change to the frame N, check the name of the current frame and obtain the default basis for the tangent space of the current frame.

Example 3.

Since the frame M was used more recently than the frame P, the vectors D_x and D_y are vectors on M while the vector D_z is a vector on P.

The vectors D_x, D_y and D_z are now all defined on P.
