    Parameters
    ----------
    file : str or file-like object
        Either the file name (string) or an open file (file-like object)
        where the data will be saved. If file is a string, the ``.npz``
        extension will be appended to the file name if it is not already
        there.
    matrix: spmatrix or sparray
        The sparse matrix or array to save.
        Supported formats: ``csc``, ``csr``, ``bsr``, ``dia`` or ``coo``.
    compressed : bool, optional
        Allow compressing the file. Default: True

    See Also
    --------
    scipy.sparse.load_npz: Load a sparse matrix from a file using ``.npz`` format.
    numpy.savez: Save several arrays into a ``.npz`` archive.
    numpy.savez_compressed : Save several arrays into a compressed ``.npz`` archive.

    Examples
    --------
    Store sparse matrix to disk, and load it again:

    >>> import numpy as np
    >>> import scipy as sp
    >>> sparse_matrix = sp.sparse.csc_matrix([[0, 0, 3], [4, 0, 0]])
    >>> sparse_matrix
    <Compressed Sparse Column sparse matrix of dtype 'int64'
        with 2 stored elements and shape (2, 3)>
    >>> sparse_matrix.toarray()
    array([[0, 0, 3],
           [4, 0, 0]], dtype=int64)

    >>> sp.sparse.save_npz('/tmp/sparse_matrix.npz', sparse_matrix)
    >>> sparse_matrix = sp.sparse.load_npz('/tmp/sparse_matrix.npz')

    >>> sparse_matrix
    <Compressed Sparse Column sparse matrix of dtype 'int64'
        with 2 stored elements and shape (2, 3)>
    >>> sparse_matrix.toarray()
    array([[0, 0, 3],

    Parameters
    ----------
    file : str or file-like object
        Either the file name (string) or an open file (file-like object)
        where the data will be loaded.

    Returns
    -------
    result : csc_array, csr_array, bsr_array, dia_array or coo_array
        A sparse array/matrix containing the loaded data.

    Raises
    ------
    OSError
        If the input file does not exist or cannot be read.

    See Also
    --------
    scipy.sparse.save_npz: Save a sparse array/matrix to a file using ``.npz`` format.
    numpy.load: Load several arrays from a ``.npz`` archive.

    Examples
    --------
    Store sparse array/matrix to disk, and load it again:

    >>> import numpy as np
    >>> import scipy as sp
    >>> sparse_array = sp.sparse.csc_array([[0, 0, 3], [4, 0, 0]])
    >>> sparse_array
    <Compressed Sparse Column sparse array of dtype 'int64'
        with 2 stored elements and shape (2, 3)>
    >>> sparse_array.toarray()
    array([[0, 0, 3],
           [4, 0, 0]], dtype=int64)

    >>> sp.sparse.save_npz('/tmp/sparse_array.npz', sparse_array)
    >>> sparse_array = sp.sparse.load_npz('/tmp/sparse_array.npz')

    >>> sparse_array
    <Compressed Sparse Column sparse array of dtype 'int64'
        with 2 stored elements and shape (2, 3)>
    >>> sparse_array.toarray()
    array([[0, 0, 3],
           [4, 0, 0]], dtype=int64)

    In this example we force the result to be csr_array from csr_matrix
    >>> sparse_matrix = sp.sparse.csc_matrix([[0, 0, 3], [4, 0, 0]])
    >>> sp.sparse.save_npz('/tmp/sparse_matrix.npz', sparse_matrix)
    >>> tmp = sp.sparse.load_npz('/tmp/sparse_matrix.npz')
    >>> sparse_array = sp.sparse.csr_array(tmp)
