broadcast!
broadcast!(f, dest, As...)
Like broadcast, but store the result of broadcast(f, As...) in the dest array. Note that dest is only used to store the result, and does not supply arguments to f unless it is also listed in the As, as in broadcast!(f, A, A, B) to perform A[:] = broadcast(f, A, B).
Examples
julia> foo = [1 2]
1x2 Array{Int64,2}:
1 2
julia> bar = [-1; -2]
2x1 Array{Int64,2}:
-1
-2
julia> baz = Array(Int8, (2,2));
julia> broadcast!(*, baz, foo, bar)
