Addcmul
Arguments
- self
(Tensor) the tensor to be added
- tensor1
(Tensor) the tensor to be multiplied
- tensor2
(Tensor) the tensor to be multiplied
- value
(Number, optional) multiplier for \(tensor1 .* tensor2\)
addcmul(input, tensor1, tensor2, *, value=1, out=NULL) -> Tensor
Performs the element-wise multiplication of tensor1
by tensor2
, multiply the result by the scalar value
and add it to input
.
$$
\mbox{out}_i = \mbox{input}_i + \mbox{value} \times \mbox{tensor1}_i \times \mbox{tensor2}_i
$$
The shapes of tensor
, 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_addcmul(t, t1, t2, 0.1)
}
