Do you need to use an array? That sounds better suited for a range. On Tuesday, September 13, 2016 at 10:24:15 AM UTC-7, Neal Becker wrote: > > Steven G. Johnson wrote: > > > > > > > > > On Monday, September 12, 2016 at 7:32:48 AM UTC-4, Neal Becker wrote: > >> > >> PnSeq.jl calls rand() to

[julia-users] Re: Pkg.add() works fine while Pkg.update() doesn't over https instead of git

You modified your METADATA. Did you make a package or something? The easiest thing to do would be to go to the v0.4/METADATA folder and use `git stash`. However, this will stash any of the changes you made. Did you make these changes for a reason, like you want to publish a new release for a pa

1. Jeff Bezanson and Stefan Karpinski. I kid (though that's true). It's the group of MIT students who made it. You can track the early issues and kind of see who's involved. Very early on that's probably a good indic

For gradients, check out ForwardDiff. It'll give you really fast calculations. On Tuesday, September 13, 2016 at 4:29:59 AM UTC-7, MLicer wrote: > > Dear all, > > i am wondering if there exists Julia N-dimensional equivalents to Numpy > vector field operators like gradient, divergence and curl,

[julia-users] Idea: Julia Standard Libraries and Distributions

I think one major point of contention when talking about what should be included in Base due to competing factors: 1. Some people would like a "lean Base" for things like embedded installs or other low memory applications 2. Some people want a MATLAB-like "bells and whistles" approach.

I can confirm that works. Wow, never knew that was there. It should be added to the menu. Maybe it's still considered experimental. On Monday, September 12, 2016 at 4:27:52 PM UTC-7, Uwe Fechner wrote: > > It works for me: > Try to open the command palette (Cmd-Shift-P on mac, I guess Ctrl-Shift-

Sometime last week I threw up a logo idea, and a ton of other really cool ideas followed. Now that we have so many awesome choices due to a previous thread , it's hard to pick. Help us choose the JuliaDiffEq logo by going to this issue

For SGE, a lot of systems let you ssh into the node and use htop. That will show you a lot of information about the node, and can help you find out which process is using up what about of memory (note, this check only works in real-time so your computational has to be long enough). On Monday, S
