This is about twice as fast with, with @simd: function f2(a, p) @assert length(a) == length(p) s = 0.0 @simd for i in eachindex(a) @inbounds s += abs((a[i] - p[i])/a[i]) end return 100s/length(a) end julia> @benchmark f(a, p) BenchmarkTools.Trial: samples:

I need to write a 4 dimensional a array to file and use write(f, a). What is the canonical binary representation of a ? It looks like the the line above is equivalent to write(f, reshape(a, prod(size(a Is the

Re: [julia-users] Filtering DataFrame with a function
