mindspore.ops.acos

mindspore.ops.acos(x)[source]

Computes arccosine of input tensors element-wise.

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

Parameters

x (Tensor) – The shape of tensor is \((N,*)\) where \(*\) means, any number of additional dimensions. The data type should be one of the following types: float16, float32, float64.

Returns

Tensor, has the same shape and dtype as x.

Raises

TypeError – If x is not a Tensor.
TypeError – If dtype of x is not float16, float32 or float64.

Supported Platforms:: Ascend GPU CPU

Examples

>>> x = Tensor(np.array([0.74, 0.04, 0.30, 0.56]), mindspore.float32)
>>> output = ops.acos(x)
>>> print(output)
[0.737726  1.5307857 1.2661036 0.9764105]
