[julia-users] Re: Dimension mismatch error in Julia!​

Looks like a couple things going on here: - The error is due to a mix of hcat and vcat in the definition of f; replacing it with either *f(x,y)= [y;-w^2*sin(x)-u*w^2*cos(x); -2γ*y];* or *f(x,y)= [y, -w^2*sin(x)-u*w^2*cos(x), -2γ*y];* will fix this error. I predict other errors down the line: -

[julia-users] ANN/RFC: Termbox.jl

Termbox.jl (https://github.com/jgoldfar/Termbox.jl) is a wrapper for Termbox, a lightweight text-based user interface library. OSX and Linux are currently supported, and the low-level interface is complete enough to re-implement the demo from the original package (see test/outputexample.jl.) I

[julia-users] Re: ANN: Yeppp.jl

Many thanks for the package; particularly interesting that Yeppp! is faster than devectorized Julia code as well, when it is able to outperform Julia. In case anyone else finds it useful, I added a small benchmark here at this gist: https://gist.github.com/jgoldfar/7cb34d8469f92d36fb47 -Max On

Been working off of the examples (and the docs, which I understand are in flux) but running into an issue I'm not sure is worth reporting, or can be fixed. Don't honestly know where to start, if anyone has an idea

Yes [1] I've been bitten by this before as well; it's unfortunate. Is there perhaps some way to change some command line arguments after starting Julia? [1] http://unix.stackexchange.com/questions/14887/the-way-to-use-usr-bin-env-sed-f-in-shebang/14892#14892 On Thursday, May 19, 2016 at 2:35:27

[julia-users] Anyone running into a build error on latest master on OSX?

Not sure if this is the place for this kind of discussion, but here goes. Been building from source from master periodically and enjoying poking around in the source, but have run into an issue apparently due to the updated LLVM version, and am wondering if anyone else is having similar issues.

[julia-users] Creating closures referencing type parameters recently broken

Not sure if anyone else has (perhaps poorly conceived, but used to work) code like this: function dotest{T}(x::T) subf(x2::T)=println(x, ", ", x2) subf(one(x)) end dotest(1.1) (reduced from a more complicated construction, in which "subf" is mapped onto multiple arrays.) Some change in

Re: [julia-users] Creating closures referencing type parameters recently broken

Ah, I do recall reading that thread but didn't make the connection. I thought I'd built a version recent enough that it should have already broken due to that, but I guess not. Thanks for your help! -Max Goldfarb > On Feb 13, 2016, at 6:33 PM, Kristoffer Carlsson > wrote: > > Jeff said this.

[julia-users] Updated performance tips?

I've really been enjoying writing Julia code as a user, and following the language as it develops, but I have noticed that over time, previously fast code sometimes gets slower, and (impressively) previously slow code will sometimes get faster, with updates to the Julia codebase. No complaint he
