atan(input: Tensor)

Element-wise inverse tangent in radians.

Alias of arctan. Returns values in $(-\pi/2, \pi/2)$ .

inputTensor

Input tensor.

Tensor

Element-wise result with the same shape as input.

Mathematical definition:

\text{out}_i = \arctan(\text{input}_i)

Gradient: $1 / (1 + x^{2})$ .
