Allocations when creating array

[giordano]

@CarlosContrerasQ12

but when I am doing it in the for loop memory starts collapsion because the garbage collector do not removes it fast enough, and when I do it manually it slows down my code

I don’t see that, with your code I get:

julia> for _ in 1:10
           @time resp=simulate_N_paths(1000,1001);
       end
