mindspore.numpy.arctan

mindspore.numpy.arctan(x, dtype=None)[源代码]

Trigonometric inverse tangent, element-wise.

The inverse of tan, so that if \(y = tan(x)\) then \(x = arctan(y)\).

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 GPU CPU

Examples

>>> import mindspore.numpy as np
>>> x = np.arange(5).astype('float32')
>>> print(np.arctan(x))
