def METHOD_NAME(*structure):
    """Create a sparse binary adjacency/neighbors matrix.
    Parameters
    ----------
    *structure : list
        The adjacency along each dimension. Each entry can be:
        - ndarray or scipy.sparse.spmatrix
            A square binary adjacency matrix for the given dimension.
            For example created by :func:`mne.channels.find_ch_adjacency`.
        - int
            The number of elements along the given dimension. A lattice
            adjacency will be generated, which is a binary matrix
            reflecting that element N of an array is adjacent to
            elements at indices N - 1 and N + 1.
    Returns
    -------
    adjacency : scipy.sparse.coo_matrix, shape (n_features, n_features)
        The square adjacency matrix, where the shape ``n_features``
        corresponds to the product of the length of all dimensions.
        For example ``len(times) * len(freqs) * len(chans)``.
    See Also
    --------

    mne.channels.read_ch_adjacency
    Notes
    -----
    For 4-dimensional data with shape ``(n_obs, n_times, n_freqs, n_chans)``,
    you can specify **no** connections among elements in a particular
    dimension by passing a matrix of zeros. For example:
    >>> import numpy as np
    >>> from scipy.sparse import diags
    >>> from mne.stats import combine_adjacency
    >>> n_times, n_freqs, n_chans = (50, 7, 16)
    >>> chan_adj = diags([1., 1.], offsets=(-1, 1), shape=(n_chans, n_chans))
    >>> combine_adjacency(
    ...     n_times,  # regular lattice adjacency for times
    ...     np.zeros((n_freqs, n_freqs)),  # no adjacency between freq. bins
    ...     chan_adj,  # custom matrix, or use mne.channels.find_ch_adjacency
    ...     )  # doctest: +NORMALIZE_WHITESPACE
    <5600x5600 sparse matrix of type '<class 'numpy.float64'>'
            with 27076 stored elements in COOrdinate format>
