[julia-users] Help on building Julia with Intel MKL on Windows?

Anybody knows how to build Julia with Intel MKL on Windows? I found the article below but it is for Linux. https://software.intel.com/en-us/articles/julia-with-intel-mkl-for-improved-performance Thanks!

[julia-users] How to deal with methods redefinition warnings in 0.5?

I see the new behavior in 0.5 when I do include("file.jl") again on REPL, I get a bunch of warnings about methods definition overwritten. What can I do? Am I supposed to be able to include("file.jl") after I modify something in it?

I have had good results with the following: put test code in its own module, say TestModule.jl, which uses/imports ModuleA. Then the REPL session looks like this: include("ModuleA.jl"); include("ModuleB.jl"); include("TestModule.jl") TestModule.run() repeated over and over. Done in this

[julia-users] Workflow question - reloading modules

Hi all, If I'm debugging a single module within the REPL, it is sufficient to just `import Module`, test the things I want to test, make changes to the code in Module, then `reload("Module")`. Now, I'm trying to debug code that uses two modules: ModuleA and ModuleB (ModuleA uses ModuleB).

Maybe PlotlyJS.jl can provide the mapping functionality you need? It allows you to create chloropleth maps as well as scatter plots (line, bubble, or dots) on top of maps.

In fact I was going to suggest you to register Luxor,jl but forgot it... Very convenient layer on top of Cairo.jl. It is really simple to work with rasterized maps, just calculate proper transform matrices and you can switch between normalized, image and UTM coordinates with setmatrix(). The

[julia-users] How to write a binary data file? (Matlab to Julia translation)

Hi, I'm translating matlab code (a wrapper for Laurens van der Maaten's Barnes-Hut t-sne code) in order to learn Julia. Within the code, data are saved as .dat file to then be read by a windows executable. The Matlab code (which works on my system) writes the data this way: * fwrite(h, n,

The problem is the initial vector v0 is zero! (This was the first iteration of an outer convergence loop; the idea is to reuse previous results of the outer loop via v0.) Here is a self-contained code that exhibits it. It does not have LinearMaps, which was not relevant. n = 241 M =

I'm not on a Mac so it's hard for me to know, but maybe the Homebrew GTK is missing theme files? Or maybe the theme files are supposed to be present in the OS, but can't be found in MacOSX? The next post is showing that there's a clash: you have two libgio's (one provided by Julia, one not),

[julia-users] Re: Error in call to eigs--0 index in arpack wrapper

In particular, the wrappers in v0.4 did not check the error returns from Arpack code, so if you passed in a zero starting vector (which is a mistake) you would get the unhelpful result you reported. With v0.5 you will get a generic error exception. The starting vector is used to seed the

[julia-users] Re: Error in call to eigs--0 index in arpack wrapper

It would be helpful if you could provide a self-contained example. Also, would it be possible to try out the release candidate for 0.5. We have made a few changes to the ARPACK wrappers so it would be useful to know if is only happening on 0.4. Thanks. On Saturday, September 10, 2016 at

Perhaps many of you have already seen this, but Julia enters top 50 on the TIOBE index for the first time! In fact their September headline is exactly that and they believe it will only get better in the coming few months! That might just line up well with Julia 1.0 next year.
