bigarray: In-place .append()
ca064f75 (bigarray: Support resizing in-place) added O(1) in-place BigArray.resize() which makes possible for users to append data to BigArray in O(δ) time. But it is easy for people to make off-by-one mistakes when calculating indices for append. So provide a convenient BigArray.append() which simplifies the following A # ZBigArray e.g. of shape (N, 3) values # ndarray to append of shape (δ, 3) n, δ = len(A), len(values) # length of A's major index =N A.resize((n+δ, A.shape[1:])) # add δ new entries ; now len(A) =N+δ A[-δ:] = values # set data for last new δ entries into A.append(values) /cc @klaus
