{{alias}}( x, dims, k, writable )
    Returns a view of the diagonal of a matrix (or stack of matrices).

    The order of the dimension indices contained in `dims` matters. The first
    element specifies the row-like dimension. The second element specifies
    the column-like dimension.

    Each provided dimension index must reside on the interval [-ndims, ndims-1].

    The diagonal offset `k` is interpreted as `column - row`. Accordingly,
    when `k = 0`, the function returns the main diagonal; when `k > 0`, the
    function returns the diagonal above the main diagonal; and when `k < 0`,
    the function returns the diagonal below the main diagonal.

    The returned ndarray is a *view* of the input ndarray. Accordingly,
    writing to the original ndarray will mutate the returned ndarray and
    vice versa.

    The `writable` parameter only applies to ndarray constructors supporting
    read-only instances.

    Parameters
    ----------
    x: ndarray
        Input array.

    dims: ArrayLikeObject<integer>
        Dimension indices defining the plane from which to extract the diagonal.

    k: integer
        Diagonal offset.

    writable: boolean
        Boolean indicating whether the returned ndarray should be writable.

    Returns
    -------
    out: ndarray
        Output array view.

    Examples
    --------
    > var x = {{alias:@stdlib/ndarray/array}}( [ [ 1.0, 2.0 ], [ 3.0, 4.0 ] ] )
    <ndarray>[ [ 1.0, 2.0 ], [ 3.0, 4.0 ] ]
    > var y = {{alias}}( x, [ 0, 1 ], 0, false )
    <ndarray>[ 1.0, 4.0 ]
