Mismatch raises a ValueError as described in the block docstring below. The entire index (rather than just the depth) needs to be calculated for each innermost list, in case an error needs to be raised, so that the index of the offending list can be printed as part of the error. Parameters ---------- arrays : nested list of arrays The arrays to check parent_index : list of int The full index of `arrays` within the nested lists passed to `_block_check_depths_match` at the top of the recursion. Returns ------- first_index : list of int The full index of an element from the bottom of the nesting in `arrays`. If any element at the bottom is an empty list, this will refer to it, and the last index along the empty axis will be None. max_arr_ndim : int The maximum of the ndims of the arrays nested in `arrays`. final_size: int The number of elements in the final array. This is used the motivate the choice of algorithm used using benchmarking wisdom. z{} is a tuple.

These help in nested concatenation. Returns ------- shape: tuple of int This tuple satisfies:: shape, _ = _concatenate_shapes([arr.shape for shape in arrs], axis) shape == concatenate(arrs, axis).shape slice_prefixes: tuple of (slice(start, end), ) For a list of arrays being concatenated, this returns the slice in the larger array at axis that needs to be sliced into. For example, the following holds:: ret = concatenate([a, b, c], axis) _, (sl_a, sl_b, sl_c) = concatenate_slices([a, b, c], axis) ret[(slice(None),) * axis + sl_a] == a ret[(slice(None),) * axis + sl_b] == b ret[(slice(None),) * axis + sl_c] == c These are called slice prefixes since they are used in the recursive blocking algorithm to compute the left-most slices during the recursion. Therefore, they must be prepended to rest of the slice that was computed deeper in the recursion. These are returned as tuples to ensure that they can quickly be added to existing slice tuple without creating a new tuple every time. c � �� g | ] }|� �� S r r )rK rO rE s �r rM z'_concatenate_shapes.<locals>.<listcomp>W s �� �5�5�5�U�U�4�[�5�5�5r r Nr c 3 �V �K � | ]#}|d �� �k p|�dz d � �k V � �$d S )Nr r )rK rO rE �first_shape_post�first_shape_pres ���r r^ z&_concatenate_shapes.<locals>.<genexpr>^ sf �� � � � C� C�27� ��$��<�?� *� .� ��a����>� -� -� C� C� C� C� C� Cr z/Mismatched array shapes in block along axis {}.c �6 � g | ]\ }}t ||� � f��S r )rT )rK �start�ends r rM z'_concatenate_shapes.<locals>.<listcomp>f s9 � � >� >� >�$�%�� �U�C�(�(�*� >� >� >r )�anyrS r\ �sumr| �zip) rU rE � shape_at_axis� first_shaperO �offsets_at_axis�slice_prefixesr� r� s ` @@r �_concatenate_shapesr� 3 s8 ���� �H 6�5�5�5�f�5�5�5�M� ��)�K�!�%�4�%�(�O�"�4��6�7�7�+�� � C� C� C� C� C� C�;A� C� C� C� C� C� L�� =� D� D�T� J� J�L� L� L� ��M� 2� 2� 4� 4�{�4��6�7�7�7K� K�E�!�-�0�0�O�>� >�(+�Q�C�/�,A�,;�)=� )=�>� >� >�N� �.� � r c �4 ���� ��k rtt ���fd�| D � � � \ }}} ��z �z }t ||� � \ }}d� t ||� � D � � }t j t j | � � } ||| fS t | �� � } | j dg| gfS )a Returns the shape of the final array, along with a list of slices and a list of arrays that can be used for assignment inside the new array Parameters ---------- arrays : nested list of arrays The arrays to check max_depth : list of int The number of nested lists result_ndim : int The number of dimensions in thefinal array.

Blocks in the innermost lists are concatenated (see `concatenate`) along the last dimension (-1), then these are concatenated along the second-last dimension (-2), and so on until the outermost list is reached. Blocks can be of any dimension, but will not be broadcasted using the normal rules. Instead, leading axes of size 1 are inserted, to make ``block.ndim`` the same for all blocks. This is primarily useful for working with scalars, and means that code like ``np.block([v, 1])`` is valid, where ``v.ndim == 1``. When the nested list is two levels deep, this allows block matrices to be constructed from their components. .. versionadded:: 1.13.0 Parameters ---------- arrays : nested list of array_like or scalars (but not tuples) If passed a single ndarray or scalar (a nested list of depth 0), this is returned unmodified (and not copied). Elements shapes must match along the appropriate axes (without broadcasting), but leading 1s will be prepended to the shape as necessary to make the dimensions match. Returns ------- block_array : ndarray The array assembled from the given blocks. The dimensionality of the output is equal to the greatest of: * the dimensionality of all the inputs * the depth to which the input list is nested Raises ------ ValueError * If list depths are mismatched - for instance, ``[[a, b], c]`` is illegal, and should be spelt ``[[a, b], [c]]`` * If lists are empty - for instance, ``[[a, b], []]`` See Also -------- concatenate : Join a sequence of arrays along an existing axis. stack : Join a sequence of arrays along a new axis. vstack : Stack arrays in sequence vertically (row wise). hstack : Stack arrays in sequence horizontally (column wise). dstack : Stack arrays in sequence depth wise (along third axis). column_stack : Stack 1-D arrays as columns into a 2-D array. vsplit : Split an array into multiple sub-arrays vertically (row-wise). Notes ----- When called with only scalars, ``np.block`` is equivalent to an ndarray call. So ``np.block([[1, 2], [3, 4]])`` is equivalent to ``np.array([[1, 2], [3, 4]])``. This function does not enforce that the blocks lie on a fixed grid. ``np.block([[a, b], [c, d]])`` is not restricted to arrays of the form:: AAAbb AAAbb cccDD But is also allowed to produce, for some ``a, b, c, d``:: AAAbb AAAbb cDDDD Since concatenation happens along the last axis first, `block` is _not_ capable of producing the following directly:: AAAbb cccbb cccDD Matlab's "square bracket stacking", ``[A, B, ...; p, q, ...]``, is equivalent to ``np.block([[A, B, ...], [p, q, ...]])``. Examples -------- The most common use of this function is to build a block matrix >>> A = np.eye(2) * 2 >>> B = np.eye(3) * 3 >>> np.block([ ... [A, np.zeros((2, 3))], ... [np.ones((3, 2)), B ] ... ]) array([[2., 0., 0., 0., 0.], [0., 2., 0., 0., 0.], [1., 1., 3., 0., 0.], [1., 1., 0., 3., 0.], [1., 1., 0., 0., 3.]]) With a list of depth 1, `block` can be used as `hstack` >>> np.block([1, 2, 3]) # hstack([1, 2, 3]) array([1, 2, 3]) >>> a = np.array([1, 2, 3]) >>> b = np.array([4, 5, 6]) >>> np.block([a, b, 10]) # hstack([a, b, 10]) array([ 1, 2, 3, 4, 5, 6, 10]) >>> A = np.ones((2, 2), int) >>> B = 2 * A >>> np.block([A, B]) # hstack([A, B]) array([[1, 1, 2, 2], [1, 1, 2, 2]]) With a list of depth 2, `block` can be used in place of `vstack`: >>> a = np.array([1, 2, 3]) >>> b = np.array([4, 5, 6]) >>> np.block([[a], [b]]) # vstack([a, b]) array([[1, 2, 3], [4, 5, 6]]) >>> A = np.ones((2, 2), int) >>> B = 2 * A >>> np.block([[A], [B]]) # vstack([A, B]) array([[1, 1], [1, 1], [2, 2], [2, 2]]) It can also be used in places of `atleast_1d` and `atleast_2d` >>> a = np.array(0) >>> b = np.array([1]) >>> np.block([a]) # atleast_1d(a) array([0]) >>> np.block([b]) # atleast_1d(b) array([1]) >>> np.block([[a]]) # atleast_2d(a) array([[0]]) >>> np.block([[b]]) # atleast_2d(b) array([[1]]) i )� _block_setup�_block_slicing�_block_concatenate)r4 � list_ndimrV rp s r r r � sQ � �l 2>�f�1E�1E�.�F�I�{�J� �:� � �/�/� �f�i��=�=�=�!�&�)�[�A�A�Ar c �� � t | � � \ }}}t |� � }|r7|d �/t d� t |� � � � � � �t ||� � }| |||fS )zD Returns (`arrays`, list_ndim, result_ndim, final_size) rg NzList at {} cannot be empty)re r rS r\ rb �max)r4 � bottom_index�arr_ndimrp r� rV s r r� r� o s� � � *C�6�)J�)J�&�L�(�J��L�!�!�I�� � �R�(�0�� (� /� /�#�L�1�1� � � � � � �h� �*�*�K� �9�k�:� 5�5r c �J � t | ||� � \ }}} t j d� | D � � � }t d� | D � � � � }t d� | D � � � � }|r|sdnd}t j |||�� � } t || � � D ]\ } } | | t f| z < �| S )Nc � � g | ] }|j �� S r )r7 rJ s r rM z"_block_slicing.<locals>.<listcomp>� s � � :� :� :�C�c�i� :� :� :r c 3 �0 K � | ]}|j d V � �dS )� F_CONTIGUOUSN��flagsrJ s r r^ z!_block_slicing.<locals>.<genexpr>� �) � � � �>�>��#�)�N�+�>�>�>�>�>�>r c 3 �0 K � | ]}|j d V � �dS )� C_CONTIGUOUSNr� rJ s r r^ z!_block_slicing.<locals>.<genexpr>� r� r �F�C)rO r7 �order)r� r) � result_type�all�emptyr� �Ellipsis) r4 r� rV rO r� r7 �F_order�C_orderr� r$ r� rL s r r� r� � s� � � 1�� �;� (� (��E�6�6� �O� :� :�6� :� :� :� ;�E� �>�>�v�>�>�>�>�>�G��>�>�v�>�>�>�>�>�G�� 3�7� 3�C�C��E� �Y�U�%�u� =� =� =�F� �f�f�-�-� .� .�� �3�*-���{�Y�&�'�'� �Mr c �\ � t | ||� � }|dk r|� � � }|S )Nr )r� rt )r4 r� rV r$ s r r� r� � s0 � � �F�I�{� 3� 3�F��A�~�~� ��� � �� �Mr )NN)r N)r )0�__all__r� ry r� �warningsrZ r r) r � multiarrayr r r r �_from_nx�partial�array_function_dispatchr r r& r r, r r5 r; r r rG r �getattrrq rk r rl r@ r� rb re rw r| r� r� r� r� r r� r� r� r r r �<module>r� s� �� � � �� � � � � � � � � ���� ���� � � � � � � � � � � � � ?� ?� ?� ?� ?� ?� ?� ?� ?� ?� %� %� %� %� %� %� ,�)�+� �%�g�7� 7� 7� �� � � ��/�0�0�2� 2� 1�0�2�j� � � ��/�0�0�2� 2� 1�0�2�j� � � ��/�0�0�@� @� 1�0�@�F� � � '+�D� -� -� -� -� -� ��,�-�-� �{� EB� EB� EB� EB� .�-�EB�P ��,�-�-� �{� BF� BF� BF� BF� .�-�BF�J� �$�� � � � � ��*�+�+�T9�T�;� T9� T9� T9� T9� ,�+�T9�t ��� �}�h�m�<�<����� �}�h�m�<�<���w�x�+�$�h�&:�<� <� � � � � 46� I1� I1� I1� I1�X8� 8� 8� .� .� .�6!� 6!� 6!�r2&� 2&� 2&� 2&�j0� 0� 0� 0�&� � � ��*�+�+�hB� hB� ,�+�hB�^6� 6� 6�"� � �&� � � � r
