is_packed

t3toolbox.backend.ut3_operations.is_packed(vectors)

def is_packed(
        vectors,  # a packed supercore array (single ndarray) OR a ragged len=d sequence of per-mode vectors
) -> bool:        # True if already packed (one array), False if a ragged list/tuple of d per-mode arrays

Whether mode vectors are packed (a single supercore-shaped ndarray) or ragged (a len=d sequence of per-mode arrays of differing widths). The uniform sampling ops infer packedness from this and mirror it – packed in -> packed out, ragged in -> ragged out.

Return type:

bool
