t3toolbox.manifold.CorewiseGeometry.frame(x)

def frame(
        self,
        x:  t3.TuckerTensorTrain,
) -> bvf.T3Frame:  # the (U, G, G, G) non-orthonormal frame at x

The core-parameter frame at x: (U, G, G, G) (down/left/right all the TT cores G).

Parameters:

x (TuckerTensorTrain)

Return type:

T3Frame
