I have started using Julia roughly two summers ago. I have been visiting
this forum ever since looking for answers and tips. You guys have been

I asked this question a while ago. Has anybody tried to use the ArrayFire
library from Julia, or is anybody working on a wrapper? ArrayFire has
released version 3.
Thanks for the suggestions.
I agree with cormu...@mac.com. I see it as a web based publication of some
kind. Whether we communicate the new issue using RSS feed or e-mailing TOC
is something to think about. That would address the preference of Tamas.
Maybe we want to have both, so that people
work through it.

Happy new year!!
I am encountering a very odd fft error. I am trying fft NxN data. The data
is produced using a mathematical equation. After debugging I have found
that the following expression is gives NaN error:

where X and Y are Array{Floa
how would one clear values of variable, or change the type: for instance if

Second question is if

Arrayfire has a large library for GPU computing. They have decided to make

will write some sort of wrapper to use the Arrayfire library in Julia.

The documentation says:
filter(function, collection)
Return a copy of collection, removing elements for which function is false.
For associative collections,
the function is passed two arguments (key and value).
how to write the fucntion? I am trying to get elements which are nonzero.

I am having exactly the same problem: LibCurl and Nettle does not build and
I suppose this is causing the kernel in iJulia to repeatedly die. The irony
is that I just re-installed my OS.

Is there way of calculating limit of a function?
I have tried SymPy Package. But it unfortunately doesnot compute limit for
bessel function.
r= Sym("r")
limit(besselj(1, r)/r, r, 0)
returns the following error:
`besselj` has no method matching besselj(::Int64, ::Sym)

You are correct. I was able to reproduce the error by first writing yticks
= ([1, 2, 3]) and then correcting the syntax to yticks ([1, 2, 3]) returns
the error.

I like it. I think the search will be a bit more useful if it also does

I have finished writing my first real Julia program (800 lines of code). I
am using it to solve a nonlinear optics problem. It took me roughly eight
days to move my code from Mathematica to Julia. I have spent most of my
time (five out of eight days) in debugging and playing with different

I have a simple question: How do I select all columns or particular columns
from a matrix. it is very straightforward to select a row. I have been
struggling for the last two hours. how do I do this? the manual does not
seem to talk about it. or am I missing it?
I need help in understanding what am I doing wrong in each of the following
cases:
@everywhere function f2 (x, y)
return x + 1 + y
end
dArray = dzeros(5)
@parallel for i=1:5
b= map(f2, [x, x])
push!(dArray, b)
end
dArray returns are still zero and the dimensions have not changed

Okay. I skimmed through the documents and previous questions and I am
confused. I have a few questions:
1. One may do some sequential evaluation followed by parallel operation on
the same set of data. I see how one creats a distributed array. But how
would I distribute already existing variable
