If we have array equation like x = x + y this creates extra memory allocation. Does the following do in place update x .= x + y How to find out if the update is happening in place ?

Julia is doing everything correctly. Operation a + b requires 1 allocation to create a new array and c = ... binds variable c to this new array. Binding does not require allocation. In other words, c = a + b is roughly equivalent to temp = Vector{Float64}(undef, 100) for i in 1:100 temp[i] = a[…
