ufv_reciprocal_weights

t3toolbox.backend.ufv_operations.ufv_reciprocal_weights(weights)

def ufv_reciprocal_weights(weights: UT3FrameWeightsData) -> UT3FrameWeightsData:

Elementwise 1/w on the real slots of all four families (masks unchanged); the padding stays a canonical, finite zero rather than becoming inf. See ut3_reciprocal_weights – this is the Grasedyck-Kramer path (from_ut3weights(from_ut3svd(x)).reciprocal()), so the guard is on the headline route. Real-slot zeros are deliberately NOT guarded.

Parameters:

weights (UT3FrameWeightsData)

Return type:

UT3FrameWeightsData
