mindspore.ops.csr_atan(x: CSRTensor)[source]

Computes the trigonometric inverse tangent of the input element-wise.

\[out_i = an^{-1}(x_i)\]
Parameters

x (CSRTensor) – The data type should be one of the following types: float16, float32.

Returns

A CSRTensor, has the same type as the input.

Raises

  • TypeError – If x is not a CSRTensor.

  • TypeError – If dtype of x is not float16 or float32.

Supported Platforms:

Ascend GPU CPU

Examples

>>> from mindspore import dtype as mstype
>>> from mindspore import Tensor, ops, CSRTensor
>>> indptr = Tensor([0, 1, 2, 2], dtype=mstype.int32)
>>> indices = Tensor([3, 0], dtype=mstype.int32)
>>> values = Tensor([-1, 2], dtype=mstype.float32)
>>> shape = (3, 4)
>>> x = CSRTensor(indptr, indices, values, shape)
>>> output = ops.csr_atan(x)
>>> print(output.values)
