Mv
mv(input, vec, out=NULL) -> Tensor
Performs a matrix-vector product of the matrix input
and the vector
vec
.
If input
is a \((n \times m)\) tensor, vec
is a 1-D tensor of
size \(m\), out
will be 1-D of size \(n\).
Examples
if (torch_is_installed()) {
mat = torch_randn(c(2, 3))
vec = torch_randn(c(3))
torch_mv(mat, vec)
}
