dpnp.arctanh

dpnp.arctanh(x, out=None, where=True, order='K', dtype=None, subok=True, **kwargs)

Computes hyperbolic inverse tangent for each element x_i for input array x.

For full documentation refer to numpy.arctanh.

Parameters:

  • x ({dpnp.ndarray, usm_ndarray}) -- Input array, expected to have numeric data type.

  • out ({None, dpnp.ndarray}, optional) -- Output array to populate. Array must have the correct shape and the expected data type.

  • order ({"C", "F", "A", "K"}, optional) -- Memory layout of the newly output array, if parameter out is None. Default: "K".

Returns:

out -- An array containing the element-wise hyperbolic inverse tangent. The data type of the returned array is determined by the Type Promotion Rules.

Return type:

dpnp.ndarray

Limitations

Parameters where and subok are supported with their default values. Keyword argument kwargs is currently unsupported. Otherwise NotImplementedError exception will be raised.
