UT3Variations.zeros

static t3toolbox.uniform_frame_variations_format.UT3Variations.zeros(uniform_variation_shapes, shape, stack_shape=(), masks=None, use_jax=False)

def zeros(

) -> 'UT3Variations':

Zero variations filling the padded supercores completely (additive identity). masks optional; None -> all-True. (See zeros_like() to take the structure – incl. gauge masks – from a UT3Frame / UT3Variations.)

Parameters:

• shape (t3toolbox.backend.common.typ.Sequence[int])

• stack_shape (t3toolbox.backend.common.typ.Tuple[int, Ellipsis])

• masks (t3toolbox.backend.common.typ.Optional[UT3VariationsMasks])

• use_jax (bool)

Return type:
