) -> 'UT3Tangent':

Transpose 𝒥ᵀ of entries_derivatives(): scatter residual jets c at index into a tangent (= apply_derivatives_transpose() with one-hot vectors). Uniform mirror of entries_derivatives_transpose().

Parameters:

• frame (UT3Frame)

• order (int)

• sum_over_probes (bool)

Return type:

UT3Tangent
