mindspore.numpy.arctanh

mindspore.numpy.arctanh(x, dtype=None)[source]

Inverse hyperbolic tangent element-wise.

Note

Numpy arguments out, where, casting, order, subok, signature, and extobj are not supported.

Parameters

x (Tensor) – Input tensor.
dtype (mindspore.dtype, optional) – Default: None. Overrides the dtype of the output Tensor.

Returns

Tensor or scalar. This is a scalar if x is a scalar.

Supported Platforms:: Ascend CPU

Examples

>>> import mindspore.numpy as np
>>> x = np.array([-0.99, -0.75, -0.5, 0, 0.5]).astype('float32')
>>> print(np.arctanh(x))
