GNU Octave 3.0 Released After 11 Years
Digana writes "GNU Octave is a free numerical computing environment highly compatible with the MATLAB language. After 11 years of development since version 2.0, stable version 3.0 released yesterday. This version is interesting because unlike other free or semi-free MATLAB competitors like Scilab, specific compatibility with MATLAB code is a design goal. This has manifested itself in goodies like better support for MATLAB's Handle Graphics, a syntax closer to MATLAB's own for many functions, and many functions from the sister project Octave-Forge ported to the core Octave project for an enriched functionality closer to the toolboxes provided by MATLAB. GUI development is underway, but still no JIT compiling, which is a show-stopper for Octave newbies coming from MATLAB with unvectorized code." -

MATLAB Programming Contest Winner Announced
gooru writes "The MATLAB programming contest winner has been announced. It is a semi-annual programming contest organized by the MathWorks. What makes the contest truly interesting is the final phase is open source. Contestants may submit as many entries as they want and can tweak other entries." -
PDL 2.4.0: Scientific Computing for the Masses
Dr. Zowie writes "Perl Data Language 2.4.0 was just released; get it here. This release includes even more powerful array slicing, a complete GIS cartography package, API access to the Gnu Scientific Library, and a host of other goodies. Between PDL and its less-mature siblings Numeric Python and Octave, the established commercial languages' days appear numbered." -
Use of Math Languages and Packages in Research?
CEHT asks: "As a research programmer at the university, I have encountered numerous times when I need to choose which language(s) or package(s) to use for different projects. Tradeoffs and performance issues have to be considered: results from one package may be more compatible with the data from other researchers, another package may find the solution faster and use less resources, and so forth. Maple, Matlab, Magma, and Mathematica are among the most well-known packages. Libraries such as IMSL is also popular. Of course, there are smaller (and mostly free) packages that tend to target specific types of problem, such as LiDIA, Singular, and LAPACK. The question is, how useful are these [and other] math packages? Do researchers use only one or two packages for most of their projects? Or do people like to mix things a little by pulling the strength of different packages together to solve a math problem? If not, do researchers write C/C++ programs and use GMP or Matpack to solve math problems?" -
Mathematica vs. Matlab?
Ninnux asks: "I wanted to find out from the community which was the better mathametics modeling package: Mathematica or Matlab. The cancer center I research and program for is considering purchasing a license set. I'll be working with Bayesian machine learning and other bioinformatic approaches for hormone pathway modeling. I know Matlab has various toolboxes that would be rather useful, but I'd like to hear what people think." While I'm sure direct comparisons will be made, I think focusing on the specific niche will help Ninnux the most; so, how well does each piece of software handle Bayesian functions and other bioinformatic computations? -
Apple Quickies Comin' At Ya
There are a few new product announcements recently: MATLAB for Mac OS X is available; fink for 10.2 is available for testing; Intuit has announced QuickBooks for Mac OS X; and PowerLogix has announced even more upgrades, including dual processor upgrades. And one user notes, "I wonder if the /. effect could drain the batteries of this Newton quickly?" -
MATLAB for Mac OS X Announced
FunkDaddy writes "The MathWorks today announced its intention to make MATLAB, the industry's leading technical computing software, available on Mac OS X, with the next release of the MathWorks product line. With MATLAB on Mac OS X, users will be able to use powerful, sophisticated technical computing tools in a graphical and intuitive environment. You hear that mac-geek-scientist-guys? Rejoice!" It looks like perhaps that survey did some good. -

Realtime Signal Processing for Unix?
Christoph Zrenner asks: "I'm a UK medical student with a serious research interest in "how to interface neurons with computers". We do a major project in our third year and I'm interfacing an eel spinal cord (8 analog inputs, 12 analog outputs) to simulate the eel's movements on a computer. The processing needs to happen in real-time (1ms delay) so that the cord can get feedback from the computer. Having spent two days foraging through the Internet I still haven't come up with a decent solution - does anyone have any experience with this kind of thing? I was hoping to use the Matlab/Linux combination but only found an (expensive!) Realtime Windows Target Toolkit for Matlab!" -

What Does the Future Hold for GNU Octave?
nicsterrr asks: "Since returning to education and discovering the delights of signal processing and numerical computation, I have become increasingly unhappy with Matlab. Mathworks refuse to release the Linux student version of Matlab in Europe (their official reason is that apparently us Europeans would pirate it frantically if they did), and hence I have had to run the windows version with Wine (with moderate success). I (and many others) would love to use Octave as our primary numerical computation package, but it is limited in areas such as signal processing, control systems, and especially graphical functions. Their homepage does not give much insight into Octave's current development and likely future. How many people are involved in Octave, or would like to be? Am I one of many that feel a new, concerted effort should be taken to transform Octave into a complete replacement for Matlab? This is a critical piece of open source software for universities and the lack of a Matlab replacement is one of the reasons my department frowns on our requests for Linux based PCs." -
