Repeat CuArray (subtract 3 Vector from every row of nx3 matrix)

Is there any other way to subtract a vector form every row of a matrix in a fast way, without writing a new kernel (Be differentiable with Zygote)?

Use broadcasting? e.g. A .- [1 2 3] subtracts [1 2 3] from each row of an m \times 3 matrix A.
