Addr
Description
Addr
Usage
torch_addr(self, vec1, vec2, beta = 1L, alpha = 1L)
Arguments
self |
(Tensor) matrix to be added |
vec1 |
(Tensor) the first vector of the outer product |
vec2 |
(Tensor) the second vector of the outer product |
beta |
(Number, optional) multiplier for |
alpha |
(Number, optional) multiplier for |
addr(input, vec1, vec2, *, beta=1, alpha=1, out=NULL) -> Tensor
Performs the outer-product of vectors vec1
and vec2
and adds it to the matrix input
.
Optional values beta
and alpha
are scaling factors on the
outer product between vec1
and vec2
and the added matrix
input
respectively.
\mbox{out} = \beta\ \mbox{input} + \alpha\ (\mbox{vec1} \otimes \mbox{vec2})
If vec1
is a vector of size n
and vec2
is a vector
of size m
, then input
must be
broadcastable with a matrix of size
(n \times m)
and out
will be a matrix of size
(n \times m)
.
For inputs of type FloatTensor
or DoubleTensor
, arguments beta
and
alpha
must be real numbers, otherwise they should be integers
Examples
if (torch_is_installed()) {
vec1 = torch_arange(1, 3)
vec2 = torch_arange(1, 2)
M = torch_zeros(c(3, 2))
torch_addr(M, vec1, vec2)
}
