Yup you are absolutely right. Working for me as well. Thought I would give
the @time macro a try. Haven't used it before. Restarting Julia, adding
functions and running @time gives a longer elapsed time for both. Rerunning
@time returns tiny values. The time listed below is for re-entering the
functions followed by @time, which is closer to what would happen every
time I rerun a script without closing Julia. Will stick to deleteat!. Thanks
function f1(n)
x1 = rand(1:10,5);
errs = [2,4];
deleteat!(x1,errs);
end
function f2(n)
x2 = rand(1:10,5);
errs = [2,4];
for i=length(errs):-1:1
splice!(x2,errs[i])
end
end
julia> @time f1(1)
elapsed time: 0.002991644 seconds (62712 bytes allocated)
julia> @time f2(1)
elapsed time: 0.006547346 seconds (129080 bytes allocated)
