Octave and Gnuplot Coming To Android
New submitter MathIsTasty writes "Recently, it was announced on the Octave-maintainers list that a Kickstarter campaign has been launched to bring Matlab style numerical computations and graphing to Android via a 'more than' port of Octave and gnuplot. While I doubt it will be as successful as some recent games on Kickstarter, is this a reasonable way to fund free software development? Now, we just have to worry about people working on simulating solar irradiation while driving. Here is a good blog post about the project." -
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." -
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." -
Spreadsheets for Scientific Computing?
redcliffe asks: "Sometimes it's much easier to create a spreadsheet to do some mathematical calculations for physics than to create a whole new program to do the calculations. It's also handy to be able to easily change one figure and have all your other calculations update. But there a certain types of calculations that normal spreadsheet apps like KSpread don't seem to handle well. Anyone know of a spreadsheet or something similiar designed for scientific computing? I've seen GNU Octave, but that's almost like writing a whole program, and without a GUI it's hard to learn quickly." -
Free Linear Programming Software?
Chao-Kuei Hung asks: "I will be teaching a freshman level math class next semester in which half of the course deal will deal with linear programming. I found a number of linear programming software packages from this website, but none of them seems to meet any of the FSF/OSI/Debian's definition of free/open source software, although some come with source code and some cost $0 for educational use. Does there exist truely free software for this topic? Are there LP modules/plug-ins for things like octave, rlab, or R?" -
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."
