Windows XP or higher
Hello to everyone.
Due to major problems with on-line registration, the Developer has changed activation procedure. Now it is simple and (what's more important) off-line.
Please feel free to re-download the installation materials from us.
Sorry for the inconvenience.
Thank you and best regards,
GOTD project team
The software offered on the developer's website is 4.8MB while the one here is 11 MB.
Moreover, it's no match for MATLAB. A free alternative to MATLAB, which is a lot better than GAOTD today is SciLab. This can be downloaded from http://www.scilab.org/.
Free (and open source) alternatives:
Octave - mostly compatible with MatLab, allowing to combine with C++ code, works with Visual Studio (http://www.gnu.org/software/octave/)
Sage - developed at the University of Washington (http://www.sagemath.org/index.html)
SciLab - can be used for signal processing, statistical analysis, image enhancement, fluid dynamics simulations, numerical optimization, and a lot of other things. It has also a symbolic manipulations toolbox. MATLAB code, which is similar in syntax, can be converted to Scilab.
There are a bunch of others but these are more universal, popular and handy. They are featured in Wikipedia (look up "GNU_Octave", "Sage_(mathematics_software)", "Scilab"). They are not only totally free (GNU standard) but cross-platform (UNIX, Mac, Windows) and can be combined with popular commercial programming/development/math systems.
Is there anything today's giveaway has that the above-mentioned systems haven't?
This is yet another product where the developers produced it because they could, rather than looking at what's available. Most users want to do calculations, if you're online, your best bet is the free WolframAlpha, which has the power of Wolfram Mathematica behind it. If you want more capabilities and subscribe to Wolfram Alpha Pro (student rate available) by the end of the month, Wolfram will double your monthly credits for the lifetime of your subscription. Hobbyist and student prices are available for Mathematica. If you want to work offline, there's the free Microsoft Mathematics 4.0, which also accepts digital ink input (you can draw with a mouse, but it's not as convenient as a touchpad or digitizing tablet). If you want to program, besides Mathematica, your best bet is the free J programming language, which is vastly more powerful than Doronix Math Toolbox. For those familiar with APL, they not only list the language differences but have a phrase list and links to APL fonts (at the bottom of the phrase list). All of the options which I listed support numerous basic math capabilities, such as complex numbers, which Math Toolbox appears to lack.
This is to Barry, the first user to comment a post here. Barry, this is NOT why we have voting and don't take this the wrong way but this is the problem we are having with people voting thumbs down for the WRONG reasons.
If you have no use, or don't understand what the program for a certain giveaway is used for, DON'T VOTE. Instead you could leave a comment and state such but its better to just come back tomorrow. Voting is used for how well a program does at the task its trying to achieve. If a word processor is a giveaway and you found it to be very simple, almost like notepad, with say just a spell checker added in. Well then, this would account for a lackluster wordprocessor compared to others which you DO have experience with. Then vote thumbs down and make a comment on why. Now say if the same type of program you found to have a lot of features you could use and the program works great for you or is above average when compared to other wordprocessors, then give it a thumbs up and leave a comment if you choose to do so.
If people would just follow those simple rules, if you don't have a use for the program, or don't know what its used for, please don't vote. This is not a voting system on if you can use the program or not, its a voting system on how well this program is compared to others in the same field.
Go ahead and thumb me down for not rating the software itself, but why are these commenters making fools of themselves by proudly proclaiming their ignorance of this product and of mathematics in general? If you have no use for a product or know nothing about it, don't comment on it. I know this is the Facebook age where everyone thinks their opinion is special, but learn when to hold your tongue.
And pick up a non-fiction book once in a while. It won't kill you.
