torch.acos#

torch.acos(input:Tensor,*,out:Optional[Tensor])→Tensor#

Computes the inverse cosine of each element ininput.

$${\text{out}}_i={\cos }^{-1}({\text{input}}_i)$$outi​=cos−1(inputi​)

Parameters

input (Tensor) – the input tensor.

Keyword Arguments

out (Tensor,optional) – the output tensor.

Example:

>>>a=torch.randn(4)>>>atensor([ 0.3348, -0.5889,  0.2005, -0.1584])>>>torch.acos(a)tensor([ 1.2294,  2.2004,  1.3690,  1.7298])
