UT3Tangent.has_minimal_ranks

t3toolbox.uniform_manifold.UT3Tangent.has_minimal_ranks()

def has_minimal_ranks(self) -> NDArray:  # bool array, shape = frame stack C (scalar unstacked)

True (per frame-stack element) if this tangent’s frame has structurally minimal ranks. See UT3Frame.has_minimal_ranks(). Minimal rank is not a correctness precondition for the tangent ops (see the contract catalog); for the numerical check see has_numerically_minimal_ranks(). Not enforced at construction.

Return type:

NDArray
