I have a dataset with n rows and k columns I want to iterate over. What is the recommended way? Currently I would first create a n x k Matrix and then do two nested for-loops. I heard column wise is best for col in 1:k for row in 1:n ... end end I heard so that functions like eachinde…

These are the most idiomatic ways, I think: julia> a = [ 1 2 3; 4 5 6 ] 2×3 Matrix{Int64}: 1 2 3 4 5 6 julia> for i in axes(a,2), j in axes(a,1) @show j, i, a[j,i] end (j, i, a[j, i]) = (1, 1, 1) (j, i, a[j, i]) = (2, 1, 4) (j, i, a[j, i]) = (1, 2, 2) (j, i, a[j, i]) = (2, …

How to best iterate over k-dimensional collection, e.g. (n,k) matrix?

Other possible options can be found here (with bonus benchmarking, although they are probably dated):
