Usage

torch_lgamma(self)

Arguments

self

(Tensor) the input tensor.

lgamma(input, out=NULL) -> Tensor

Computes the logarithm of the gamma function on input.

$${\text{out}}_i=\log \mathrm{\Gamma }({\text{input}}_i)$$

Examples

if (torch_is_installed()) {

a = torch_arange(0.5, 2, 0.5)
torch_lgamma(a)
