The judges' decision is final.

Application: Freemat
Category: Education (& Science)
Description: FreeMat Portable is a free portable environment for rapid engineering and scientific prototyping and data processing. It is similar to commercial systems such as MATLAB from Mathworks, and IDL from Research Systems, but is Open Source. FreeMat provides visualization, image manipulation, and plotting as well as parallel programming. (from the website)
Features: (from the FreeMat FAQ)

  • N-dimensional array manipulation (by default, N is limited to 6)
  • Support for 8,16, 32, and 64 bit integer types (signed and unsigned), 32 and 64 bit floating point types, and 64 and 128 bit complex types.
  • Built in arithmetic for manipulation of all supported data types.
  • Support for solving linear systems of equations via the divide operators.
  • Eigenvalue and singular value decompositions
  • Full control structure support (including, for, while, break, continue, etc.)
  • 2D plotting and image display
  • Heterogeneous array types (called “cell arrays” in MATLAB-speak) fully supported
  • Full support for dynamic structure arrays
  • Arbitrary-size FFT support
  • Pass-by-reference support (an IDL feature)
  • Keyword support (an IDL feature)
  • Codeless interface to external C/C++/FORTRAN code
  • Native sparse matrix support
  • Function pointers (eval and feval are fully supported)
  • Classes, operator overloading
  • 3D Plotting and visualization via OpenGL
  • Handle-based graphics

Patrick, you want to win the contest, without giving other people a chance?
Or was my email recognized as spam? Billions of people wait for the next release!

Btw.: I just googled "FreeMat Portable" and this page is the first hit Smile Yippie!

Sorry, found the first bug.

One point for me Wink

If you haven't a local Freemat install, the reg keys won't be saved to \Data\settings\FreeMatPortable.reg . Sad
Fix: Move line 256 in FreematPortable.nsi above line 253 and recompile the launcher.
I'm so sorry, but I'll upload a new Dev Test next week. Maybe you can answer even though a few of my questions in the main post. Then I could compress the package.

I found this bug now, because I had a local install till today.

Hi I work in a museum and

Hi I work in a museum and integrated in our setup is a science centre where as you can guess theres scientists doing research. I know I've heard grumbles about how they need better software for analysing their data. I think thats what this app doe (Please correct if wrong). Once this app is further along I'll introduce it to them which should give you a pretty good testing base. Hope this helps.

Oh, and I think many people can use FreeMat. Even students can use it for example in vector analysis, algebra of matrices ...
You can use it as a simple calculator too, but Speedcrunch Portable is easier to use for simple tasks.

You want to learn more about Freemat? I found a tutorial: "The FreeMat Primer". You could get it from the
FreeMat Sourceforge Project Page

Suggestion

Hi Bart

This app seems like it has a very specific target group. Can I suggest maybe posting about it on forums popular with uni students or that who are likely to be studying subjects that make this app handy for them.

Good suggestion!

Well, but most of them don't know the PAF-Stuff and whether registry keys or folders are left behind.
This things could only be checked by the PortableApps.com Community (or Beta Testing Team), in my opinion.
I'll try to find more testers though.

Graphics

In case FreeMat Portable would become a Pre-Release, here are links for the splash designers:
Icon (128x128 pixels), Logo (375x111 pixels)
Well, I'm aware of the fact that FreeMat is a "Low-Priority Application". I just don't want to forget where I've found the graphics.

How to use it,

hmmm, the easiest way to learn is reading the Tutorial mentioned above.
Anyway, you could test easy calculations, like:

a=5;
b=7;
a*b/2

If you click "Workspace", you'll see all used variables (e.g. a,b).
Below is an example for a tubeplot (from the manual). Just copy and paste it to the commandline.

t=0:(2*pi/100):(2*pi);
x=cos(t*2).*(2+sin(t*3)*.3);
y=sin(t*2).*(2+sin(t*3)*.3);
z=cos(t*3)*.3;
tubeplot(x,y,z,0.14*sin(t*5)+.29,t,10);

Thanks for your testing!

I was using a >60MB home made GNU Octave portable.
I am now using Freemat (which I had never tried before).
No problem until now.

Hi Bart S. Just dropping by

Hi Bart S.

Just dropping by to see how things are going. What sort of downloads have you been getting? When this reaches pre-release I'll take it over to the science centre and see how it is received : )

Hi horusofoz,

things are going well Smile I can't say the number of downloads (it's Patrick's server). And as mentioned above, I think FreeMat isn't very popular (here at PortableApps.com) and therefore a "Low-Priority Application".
So I guess the Pre-Release won't be released soon, even if I think it's ready. It's up to John and his release team.

Hey Bart.S

Can you tell me some specific functions/uses for FreeMat Portable? Now that I work at UniSA should be easier to introduce your software to students within the relevant disciplines. Previously I found the scientists at the museum where I was working to be reluctant to try the new software. However students being generally younger I would think they would be more open to trying out new things. Additionally, students generally being low income earners one can see them being more receptive to the idea of FOSS Wink

Thanks for the response scriptdaemon :-)

However a simple bulleted list of what FreeMat Portable can do would be much more helpful. That way I can present it in a manner self explanatory as I wont be able to answer any questions other than about portability and OSS.

Thanks Smile

Beta of FreeMat 4

Has anyone tested the Beta of FreeMat 4 yet? Is it worth testing (or maybe packaging as a portable app)? Or has it some known (showstopper) bugs?

It is usable enough for you to start checking how it can be packaged as portable. But I have had problems that I can't always repeat with plotting therefore I would not release a portable version here yet.

Thanks,

took a quick look. No big changes on how it can be packaged as portable. Well, some of the regkeys changed and the directory structure is a little different.
No big deal, but it's really a beta (tests fail), so I won't release a portable version.
I'm waiting for the final 4.0 release Smile

FreeMat not booting up

I have Windows 7 OS on my new laptop but whenever I try to start up FreeMat portable I get the splash screen but the application window never comes up. Is it supposed to take a long time to start up or is there something wrong?

I have a 1.50 GHz AMD E-240 processor and 3 gigs of RAM which should be plenty of processor speed and RAM although if it's anything like MATLAB it is likely very resource intensive...I used MATLAB once in a numerical analysis class

FreeMat Portable is also in the list of running processes but again I have no application window

What version are you running?
What's your installation path?

For me FreeMat Portable starts up in less than 10 seconds.

version

installation path - G:\FreeMatPortable like usual for portable apps (G is the drive letter for my pendrive which is a Kingston DT 101 G2 with a 16 GB capacity)

as for version....since I cannot get the application window to come up I can't determine which product version I'm using but according to the "Details" tab on the "right-click--->properties" menu for the main "FreeMatPortable.exe" file it says the file version (which is the same as the product version in that menu) is 1.6.2.0

creation/modification date for the FreeMatPortable.exe file was 10/15/2010. If the version of the program on this website is newer than the one I have I'll give it a try

edit: copied newer version to pendrive and it seems to be working alright....though to test a simple 2-D plot of the y = cos(x) function between 0 and 2*pi I got a pretty rough lookin' plot that had lines instead of curves between each point of inflection in that range.....certainly makes it easier to find points of inflection but the trig functions are supposed to look curvy so my guess is that there's a special plot function to get curvy plots

edit 2: tried the same thing (the plot() command) with the tangent function with the same range of values for x and got an even stranger looking plot that resembled something more along the lines of a lopsided sine wave than a true tangent plot

Version

If you're using the PortableApps.com Platform you could hover over FreeMat Portable and it'll show the version. Without the platform you could look at FreeMatPortable\App\Appinfo\AppInfo.ini.

As for your points about the plots: Please report these to the FreeMat developers or ask on the FreeMat mailing lists. I'm not developing FreeMat, I'm just making it portable. Smile

Ah, ok.

But not many users read posts inside an outdated beta testing thread (4.0 rev 4000 is the latest version ). It's better to use the FreeMat mailing lists or the Other apps support forum.
