- crgnetworks, on 10/11/2007, -10/+50I heard the torrent versions free.
- killiansman, on 10/11/2007, -0/+25Are you sure you got the student version? Cuz I paid $99 for my student version of Matlab.
Anyway... I had never heard of R and it looks pretty sweet, I'm gonna have to give it a try. - assoffire, on 10/11/2007, -0/+21if (Sage + Scilab + R == tools)
die('Mathematica');
end - inactive, on 10/11/2007, -1/+21LaTeX.
- NGNR, on 10/11/2007, -0/+16I think that GNU Octave should have made the list.
"GNU Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with Matlab. It may also be used as a batch-oriented language."

The article lists GNU Octave. It is listed as an alternative to Scilab. - respekt, on 10/11/2007, -1/+13What you are doing is probably a violation of the license. It's not too far away from cracking the latest version out right. Have you considered some open source alternatives. GNU TeXmacs works very well for publishing documents and as a frontend for Maxima.
- mtekk, on 10/11/2007, -0/+12You could use OpenOffice as it has a great built in equation editor (OpenOffice Math).
- IAmRoot, on 10/11/2007, -0/+11I recommend fung-calc as a graphing program. http://fung-calc.sourceforge.net/
- bobbyi, on 10/11/2007, -0/+9I think the best open source alternative to Matlab is the numeric computing libraries for python, especially numpy. I needed to do some work with wavelets recently and I was just about to try to figure out the Matlab Wavelets Toolbox when I discovered the python wavelets module...
- respekt, on 10/11/2007, -1/+10I partially agree with you. Matlab is the best in its field. However I think you can accomplish pretty much anything with Scilab coupled with the other free softwares available. If you can spend a thousand or more bucks for Matlab, sure it is nice, but if you can't you have a few valid alternatives IMHO.
- don0, on 10/11/2007, -1/+10R is amazin our university uses it instead of s+. open source all the way!!!!
- rhabd0mancer, on 10/11/2007, -0/+7I haven't tried it, but MathCast is open source.
http://mathcast.sourceforge.net/home.html - NGNR, on 10/11/2007, -2/+9*****...long day.
- bootle, on 10/11/2007, -0/+6Python offers a lot in the way of scientific computation with modules such as scipy/numpy which are built around very speed compiled libraries. Plus, it's VERY easy to use python to script large existing code bases in languages like C, which are far less fun to write. I hate using shell scripts now!
I know places like Los Alamos are pushing python and other free/open software hard because they, apparently, have to pay full price for every copy of matlab, no site license or discounts. Despite all their bank (probably less every day, thanks to Iraq), that's a LOT of money. - mcm297, on 10/11/2007, -6/+12If you go nuts with all of the extra features, you can spend well-over $1000 in purchasing a student copy of Matlab (as stated above, the base copy is $99.)
- nadadingsda, on 10/11/2007, -0/+6I did most of my work in Matlab until about a year ago when I switched to Python. Python combined with NumPy, Matplotlib and some other extension modules is really powerful and can easily replace Matlab for most tasks. Compared to Matlab, Python is a much better designed programming language and coding becomes fun again. If you need a GUI you can use PyQt. For some tasks Python may be a bit slow, but it is quite easy to write an extension module in C or C++, sometimes I even write a single Qt widget in C++ and combine it with PyQt.. it just rocks!
- inactive, on 10/11/2007, -2/+7Definitely, MATLAB is the standard. You will find MATLAB at every lab or engineering organization, used in everything from aircraft controls modeling to image processing. It's a wonderful, robust tool.
- CAPSLOCKISCOOL, on 10/11/2007, -0/+5then why did he link to it in valuable mentions under number 1?
- lengau, on 10/11/2007, -1/+6I've never done this before (with any software), but you could get a virtual machine, install Win98+the software, backup the VM image, and every time the trial runs out, just refresh from the old image.
- dxbmatt, on 10/11/2007, -0/+3Excel 2007 increases the limits to 16384 columns and 1048576 rows
- respekt, on 10/11/2007, -0/+3Maxima does just that.
- assoffire, on 10/11/2007, -1/+4Apparently the commenter has never read the article.
- bchang, on 10/11/2007, -2/+5Nice, I just lost my calculator and have 5 pages of trig to do. Great replacement!!
- enervation, on 10/11/2007, -0/+3For a good,fast,GPL calculator, try "Qalculate!".
http://qalculate.sourceforge.net/index.html - kaelyiesta, on 10/11/2007, -0/+3Octave is a nice substitute for matlab. It's not on par, but its free. R rocks. It isn't meant to handle things the way matlab does, but what it is meant for, it does well.
- StrawberryMarie, on 10/11/2007, -1/+3For me it's Maxima vs Axiom. Can't decide which one should I install and learn. Do you guys have any opinions regarding this?
- vagarach, on 10/11/2007, -2/+4At university of waterloo, given the unis special relationship with Waterloo Maple, the student version of maple is just $30, and I can say, its the best $30 I've ever spent! It made the first two years of my maths degree so much easier. R is also an awesome program for doing stats.
- Pic0, on 10/11/2007, -2/+4ok graph plotting software is WinPlot
I have matlab, takes a long time to load, but it is good - SEMW, on 10/11/2007, -0/+2If you're doing a lot of data processing with large amounts of data, have you considered whether a spreadsheet is the right tool for the job? You should consider whether a database or dedicated data processing package would be more efficient.
- jjcarett, on 10/11/2007, -0/+2Axiom is much more actively developed (it was "reborn" a few years ago), while maxima has been around longer, but with less omph behind it.
For ease-of-use, assuming you're Lisp kind of person, maxima wins. For correctness, Axiom's got the edge.
[Disclaimer: I do research in computer algebra; I used to work at one of the commercial vendors] - didgital, on 10/11/2007, -1/+2Does anyone know of a spreadsheet program that's not limited to 256 col x 65000 rows? I process huge spreadsheets and I always have to chop them up. Very annoying....
- loconet, on 10/11/2007, -2/+3I use Maple regularly while at school and have yet to see something that comes even close from the open source side of things.
- maninalift, on 10/11/2007, -0/+1I don't know whether it has improved but when I last used Scilab it was slow. Unusably so.
- mtekk, on 10/11/2007, -1/+2And what does Microsoft's equation editor do then? He was most likely talking about writing up reports and such.
You realized that, never mind. - KahNeth, on 10/11/2007, -0/+1quote from maxima section of article
Valuable mentions are:
* Axiom
* Sage
* Yacas
Sage, GAP and KANT/KASH are what I tend to use the most - nkthen, on 02/26/2008, -0/+1I didn't know that there are so many Open Source software for maths...
http://www.osdw.org - Phlosten, on 10/11/2007, -1/+2I have access to the latest MSOffice and I don't use it because I don't want my documents stored in it's ridiculous proprietary formats. I value my documents and I value the freedom to be able to access them for years to come. I also like being able to run OO on whichever platform I want. The filesizes are much smaller too.
- jambarama, on 10/11/2007, -0/+1R can do everything any other stats program can do, and has been for some time. We had to use it in my econometrics class way back in 2003, and it was fine, but compared to s+ or spss, it is a royal PITA to use. Not even C is as picky on syntax as R. It does have pretty great help though, so no one much minded using it. Especially when we found out the other econometrics class was using Shazam *shudder*.
- assoffire, on 10/11/2007, -0/+0The guy wrote a quick tutorial to Maxima after this post: http://digg.com/software/A_10_minute_tutorial_for_solving_Math_problems_with_Maxima
- Lane, on 10/11/2007, -1/+1i was hoping for more of type in your calc equation and pops out the answer a kind of a program. sigh... another D is on its way.
- inactive, on 10/11/2007, -2/+2Sadly Octave is _vastly_ slower than MATLAB. Scripts that run instantaneously on MATLAB take tens of minutes on Octave (compiled with GCC4). The compatibility is decent though, except for the very different RK45 ODE solvers.
- sherifffruitfly, on 10/11/2007, -1/+1Apparently the blogger has never heard of sage.
http://en.wikipedia.org/wiki/Software_for_Algebra_and_Geometry_Experimentation - johnlande360, on 03/17/2008, -0/+0I recommend fung-calc as a graphing program. http://fung-calc.sourceforge.net
Download the latest freeware, shareware and demo software arranged by categories, including screenshots, descriptions, ratings, reviews and direct download links.
Free Software Downloads: http://www.freedownloads32.com - tyrione, on 10/11/2007, -0/+0If you're doing Dynamic Systems Analysis for Stress/Strain, Fracture, etc., then MatLab for some your Numerical Analysis and then off to Ansys, Pro/E or other for modeling.
R is a statistical analysis system designed for Social Sciences.
The others have a long way to go to do what Matlab can do.
However, the biggest barrier to all of these applications is your own professional Education. If you're not an M.E./E.E/Chem.E/etc., then you won't get the most out of MatLab. - zeroduck, on 10/11/2007, -1/+1They will. If you know how to use the tools.
But to use the tools, you generally need to know what you're doing to begin with. - kutza, on 10/11/2007, -4/+4Dear God. I may be nerdy into computers, but arguing over open source math software?
That's where I draw the line. I like getting pussy. - Farrel, on 10/11/2007, -2/+2Anybody know of an open source method to replace Microsoft Word's Equation editor? I am using Google Docs quite a bit and every now and again want to insert a formula.
- gravis86, on 10/11/2007, -4/+3Where's the Mac love? You trying to say mac users can't do math? (On second thought, don't answer the last one)
