Just for the record. To convert from Array{Array{Float64, 1}, 1} to
Array{Float64,2} you can use hcat(a...)

Yep, that was my situation: no linear algebra but a lot of grabbing columns
within for loops. Looking forward to non-copying array slices:)
Thanks,

I think comparisons between those two will depend a lot on context. If you need
to use linear algebra functions, the Array{Array{Float64, 1}, 1} approach won’t
work at all, so it’ll be infinitely slow. If you’re constantly just grabbing
columns stored that way, it might be faster since you might
I'm definitely not an expert but I thought I would chime in on your "arrays of
arrays vrs matrices" question.
I recently developed a project where I started out using:
Array{Array{Float64,1},1} as a container for a set of state vectors in an ODE
flow. This seemed most natural but I figured onc
Hey all,
I decided to start learning Julia over the weekend and am having fun so
far. I implemented the wikipedia single layer perceptron algorithm as well
as kendall's tau to see what it would be like to develop a medium sized
package in the language. Link to the repo is below (the title just p
