+============================================
+
+.. module::ulab.compare
+
+.. method:: clip(x1, x2, x3)
+
+   Constrain the values from ``x1`` to be between ``x2`` and ``x3``.
+   ``x2`` is assumed to be less than or equal to ``x3``.
+
+   Arguments may be ulab arrays or numbers.  All array arguments
+   must be the same size.  If the inputs are all scalars, a 1-element
+   array is returned.
+
+   Shorthand for ``ulab.maximum(x2, ulab.minimum(x1, x3))``
+
+.. method:: maximum(x1, x2)
+
+   Compute the element by element maximum of the arguments.
+
+   Arguments may be ulab arrays or numbers.  All array arguments
+   must be the same size.  If the inputs are both scalars, a number is
+   returned
+
+.. method:: minimum(x1, x2)
