pack_if_ragged

t3toolbox.backend.ut3_operations.pack_if_ragged(vectors, N=None)

def pack_if_ragged(
        vectors,        # packed array (returned as-is) OR ragged len=d sequence, ith elm_shape=stack+(Ni,)
        N:  int = None,  # padded length (default max Ni); ignored when ``vectors`` is already packed
) -> NDArray:            # packed, shape=(d,)+stack_shape+(N,)

Pack vectors iff ragged (a len=d sequence); an already-packed array is returned unchanged. The input side of the sampling-op packedness mirror (is_packed()).

Parameters:

N (int)

Return type:

NDArray
