T3Tangent.unstack_frame

t3toolbox.manifold.T3Tangent.unstack_frame()

def unstack_frame(self):

Unstack over the frame stack C: a C-shaped tree of single-base-point tangents.

Decomposes over frame points (“for each frame”). Each leaf is a T3Tangent with frame_stack_shape == () and tangent_stack_shape equal to this tangent’s; the leaves sit at different base points (different tangent spaces, so they are not mutually linear-algebra compatible). Inverse of stack_frame().
