I am trying to figure out the most efficient way to perform in-place array operations in Julia.
julia> a=rand(10000,10000) julia> tic(); b=sin(a); toc(); elapsed time: 1.25738114 seconds julia> tic(); map!(sin,a); toc(); elapsed time: 7.821650464 seconds julia> tic(); for i=1:length(a); a[i]=sin(a[i]); end; toc(); elapsed time: 24.993171377 seconds Nothing seems faster than creating a new array, which I'd like to avoid without slowing down the code if possible. Any ideas?
