+ Inverse hyperbolic tangent element-wise.
+
+ Parameters:
+
+ -----------
+ x : _Symbol or scalar
+ Input array.
+ out : _Symbol or scalar
+ A location into which the result is stored. If provided,
+ it must have a shape that the inputs broadcast to.
+ If not provided or None, a freshly-allocated array is returned.
+ A tuple (possible only as a keyword argument)
+ must have length equal to the number of outputs.
+ where : array_like, optional
+ Values of True indicate to calculate the ufunc at that position,
+ values of False indicate to leave the value in the output alone.
+ Returns:
+
+ -------
+ out : _Symbol or scalar
+ Array of the same shape as x. This is a scalar if x is a scalar.
+ Examples
+
+ >>> np.arctan(0.7)
