+    Returns elements from an array at the one-dimensional indices specified by ``indices`` along a provided ``axis``.
+
+    Parameters
+    ----------
+    x: array
+        input array. Must be compatible with ``indices``, except for the axis (dimension) specified by ``axis`` (see :ref:`broadcasting`).
+    indices: array
+        array indices. Must have the same rank (i.e., number of dimensions) as ``x``.
+
+        .. note::
+           This specification does not require bounds checking. The behavior for out-of-bounds indices is left unspecified.
+
+    axis: int
+        axis along which to select values. If ``axis`` is negative, the function must determine the axis along which to select values by counting from the last dimension. Default: ``-1``.
+
+    Returns
+    -------
+    out: array
+        an array having the same data type as ``x``. Must have the same rank (i.e., number of dimensions) as ``x`` and must have a shape determined according to :ref:`broadcasting`, except for the axis (dimension) specified by ``axis`` whose size must equal the size of the corresponding axis (dimension) in ``indices``.
