torch.atan2#

torch.atan2(input:Tensor,other:Tensor,*,out:Optional[Tensor])→Tensor#

Element-wise arctangent of${\text{input}}_i\mathrm{/}{\text{other}}_i$inputi​/otheri​with consideration of the quadrant. Returns a new tensor with the signed anglesin radians between vector$({\text{other}}_i,{\text{input}}_i)$(otheri​,inputi​)and vector$(1,0)$(1,0). (Note that${\text{other}}_i$otheri​, the secondparameter, is the x-coordinate, while${\text{input}}_i$inputi​, the firstparameter, is the y-coordinate.)

The shapes ofinput andother must bebroadcastable.

Parameters

• input (Tensor) – the first input tensor

• other (Tensor) – the second input tensor

Keyword Arguments

out (Tensor,optional) – the output tensor.

Example:

>>>a=torch.randn(4)>>>atensor([ 0.9041,  0.0196, -0.3108, -2.4423])>>>torch.atan2(a,torch.randn(4))tensor([ 0.9833,  0.0811, -1.9743, -1.4151])
