Those are for plotting (graphing as in data visualization). The OP is

Hello colleague,
you are aware, that the calculation of eigenvalues is not constant runtime
and depends on the input matrix? You are comparing here 0...1 with -1...1
inputs, afaics.
Yes, its just a matter of time when library support increases for web
development and it will be perfectly suitable for web and as a general
purpose language. I am definitely keeping an eye on Julia and i would love
to replace python with it. :)

The following function is one of the most difficult test functions for
univariate root finding I know of,
julia function fn(x::Real)
return log(x) + x^2/(2*exp(1)) - 2 * x/sqrt(exp(1)) + 1
end
whose exact root between 1.0 and 3.4 is sqrt(e) = 1.6487212707001282...
Working on the finite field code I found myself asking what is a Number?.
One answer is:
julia Base.subtypetree(Number)
(Number,{(Complex{Float16},{}),(Complex{Float32},{}),(Complex{Float64},{}),(
Complex{T:Real},{}),(Real,{(FloatingPoint,{(BigFloat,{}),(Float16,{}),(

I don't think your code was doing a broadcast as you didn't send to the
broadcast address. However, I've finally got something working by copying
this - http://nikhilm.github.io/uvbook/networking.html#udp.
Sender:
bcaddr = IPv4(255,255,255,255)
anyaddr = IPv4(0,0,0,0)
s = UdpSocket()
This is actually a really good question. I found myself wondering the same
thing the other day.

What I've been doing is inside of ~/.juliarc.jl check `git rev-parse
--is-inside-work-tree` and then using `git rev-parse --show-toplevel` to
modify JULIA_PKGDIR and LOAD_PATH. That way each git repository can have
its own collection of packages. I'd like to formalize this pattern so that

One way to do it is

This is a long-standing problem with OpenBLAS's default thread detection.
They start using multiple threads at a ridiculously low threshold of 4.
Yes, that's right using multiple threads for a 4x4 matrix. Here is the
two-year-old issue about the matter:

given datatype?
kind of the inverse of methods(foo)?

How is this better than just deleting the method1(::Parent) method, in
which case you will get a MethodError
Well, a MethodError could mean a lot of other things (ie typo/poor test
coverage)

I’m not in charge of the GSoC projects, so it’s hard to say.
If I recall correctly, we’ve said that we’ll only accept students who have
previously made contributions on their proposed project, so it might be worth
trying to get a start on this assuming there are no objections.

Is there a way to produce an animated plot with julia?
I am thinking of simple animations, like the one produced by
CAS softwares (maple/mathematica/sage etc)
e.g.
http://www.maplesoft.com/support/help/helpview.aspx?si=2057/file01057/plot309.gif
Gaston supports output to GIF, which you could then assemble into an
animation with an independent tool.
https://github.com/mbaz/Gaston.jl
If possible, use the development version -- the latest release is getting a
bit long in the tooth.

Matplotlib (via PyPlot) has support for generating and exporting animations
(http://matplotlib.org/examples/animation/index.html).
Thanks for the answer, pyplot looks great and seems to be the easiest way
to animate a plot.
I tried with Winston and I just managed to do a simple animation as follows:
using Winston
frame(f, u; pts = 1000, kw...) =
Curve([real(f(t,u)) for t in 0:1/pts:1],[imag(f(t,u)) for t in

No, the plugin would be in pure Julia.
The protoc compiler would send events to the plugin over stdin as it parses
the .proto file, and the plugin sends out generated code over stdout. This
exchange happens using protobuf messages. The documentation I pointed to
explains the input and output
