reciprocal

→Tensor

reciprocal(input: Tensor)

Element-wise multiplicative inverse.

Computes $1/x$ for each entry. Division by zero produces +/-inf.

inputTensor

Input tensor.

Tensor

Element-wise result with the same shape as input.

Mathematical definition:

\text{out}_i = \frac{1}{\text{input}_i}

Gradient: $-1 / x^{2}$ .

>>> import lucid
>>> x = lucid.tensor([1.0, 2.0, 3.0])
>>> lucid.reciprocal(x)
