You just need to write a function that returns false for the elements you want
to filter out. Here’s an example that does what you want:
julia> myfilter(x) = x != 0
myfilter (generic function with 1 method)
julia> A = [1, 2, 0, 4, 5, 0]
6-element Array{Int64,1}:
1
2
0
4
5
0
julia> filter(myfilter, A)
4-element Array{Int64,1}:
1
2
4
5
