True (per stack element) where the MASKED Tucker factors are tied within every sharing group – the uniform twin of t3_tucker_factors_shared() (the boolean form of ut3_sharing_residual(); a non-enforcing checker).

Parameters:

• data (t3toolbox.backend.common.typ.Tuple[NDArray, NDArray, t3toolbox.backend.common.typ.Sequence[int], t3toolbox.backend.common.typ.Tuple[NDArray, NDArray]])

• sharing (t3toolbox.backend.common.typ.Sequence)

• rtol (float)

Return type:

NDArray
