Greetings,
I have been following the development of Julia for sometime now and I am
really thrilled to know that you guys have reached version 0.3.11.
To my understanding sometime in the near future you will release the new
version 0.4.0., a version that it is supposed to bring many changes.
Hello all,
I'm trying to solve a system of equations using the Sundials package for
Julia.
The code is the following:

*import Sundials*
*function sysfn(y_in, fy_in, a_in)*
*y = Sundials.asarray(y_in)*

Good morning lads.
I was delighted to see the new version of Julia (0.3.8). Alas, when I tried
to install it my Panda Antivirus quarantined the file. It saw it as a
potential threat of high risk.
Is it possible for the developers to put some kind of signature to the file
so that it is not
Haha, I am sorry my bad. I should have mentioned the broettes also!

Hi all,
I was wondering how one can make vector fields in Julia similar to those in
Matlab. To put it simple, is there any intrinsic routine that does the job
or should we program it from scratch?
Matlab example

Looking forward for the Linux version!

A friend of mine is doing Macro, but he uses Fortran because it is very
fast compared to the others. So Fortran is still used by some people.
And yes, he uses Matlab only for plots.
Surely there must be a reason why he is not using Dynare.

Matlab has built-in functions like interp, interp1, spline etc. to do
interpolation.
Does Julia have any built-in functions that can do the same job?
P.S.1 The Grid package does not work in Julia 0.3.3
P.S.2 If Julia does not support interpolation for now, the devs must

thanks for the feedback. It appears that I have already installed `script`.
I am sure that I did not use it in the past because it did not work for

As far as `Linter` is concerned I started an issue in Github. Let us see

Maybe you need to `cd` to the specific file, so the program knows where to
look for.

Hi all,
Julia is a new language and hence not many books are published about her
(if any). I was wondering if there are plans to write any books that are
not oriented to the novice, but to those people who want to build models.
That is books with specific topics about numerical computing, and
are broken. Should improve with future versions of LLVM.

Hi,
using JuMP we have a relatively easy way to solve for non-linear problems.
Usually we have the following preamble:
#
using JuMP
using Ipopt # For any kind of constraints
m = Model(solver=IpoptSolver())
...
#
I think you should have PyPlot in front of the commands and at the very end
PyPlot.show().
I was able to create a simple graph using the following code:
#
-
import PyPlot
x = linspace(0,
()
# ===
One last question that I have is whether we can use some kind of delimiter
that can give us the result in a csv file, but not in one column, but
rather in deifferent ones.

OK, I took into consideration what people said in this group.
I changed the code (see below) and I get results.
I want to save the results in a .csv file, but instead of getting three
columns, I get all the results in one column.
sigma = 1.5; # utility parameter
delta = 0.1;
Some problems have the so-called curse of dimensionality and curse of
modeling. For this reason Bersekas and Tsimtsiklis (at MIT) introduced the
so-called Neuro-Dynamic Programing.
Does Julia offer support for the aforementioned and if not, how about the
future?
