torch_addcdiv.RdAddcdiv
Arguments
- self
(Tensor) the tensor to be added
- tensor1
(Tensor) the numerator tensor
- tensor2
(Tensor) the denominator tensor
- value
(Number, optional) multiplier for \(\mbox{tensor1} / \mbox{tensor2}\)
addcdiv(input, tensor1, tensor2, *, value=1, out=NULL) -> Tensor
Performs the element-wise division of tensor1 by tensor2,
multiply the result by the scalar value and add it to input.
Warning
Integer division with addcdiv is deprecated, and in a future release
addcdiv will perform a true division of tensor1 and tensor2.
The current addcdiv behavior can be replicated using torch_floor_divide()
for integral inputs
(input + value * tensor1 // tensor2)
and torch_div() for float inputs
(input + value * tensor1 / tensor2).
The new addcdiv behavior can be implemented with torch_true_divide()
(input + value * torch.true_divide(tensor1,
tensor2).
$$ \mbox{out}_i = \mbox{input}_i + \mbox{value} \times \frac{\mbox{tensor1}_i}{\mbox{tensor2}_i} $$
The shapes of input, tensor1, and tensor2 must be
broadcastable .
For inputs of type FloatTensor or DoubleTensor, value must be
a real number, otherwise an integer.
Examples
if (torch_is_installed()) {
t = torch_randn(c(1, 3))
t1 = torch_randn(c(3, 1))
t2 = torch_randn(c(1, 3))
torch_addcdiv(t, t1, t2, 0.1)
