ig mathematics systems like
Mathematica,
Maple or
MATLAB are extremely expensive, with prices starting at $2500, $1900 and $1900 respectively. Those prices are for the single commercial license. My interests aren't commercial, but is no non-commercial sales option. They all have Student, Government and Commercial licenses. I'd call myself a student in the wider sense, but they will want to check with my institution, which is, I guess, just myself, and I'm guessing they'd balk at that.
Since there's no money to be had in autodidacts, I either shell out the big bucks or make do with systems such as
FreeMat,
Octave or
Scilab. These seem to be good tools, which I've only dabbled with a touch, but they're clearly not on the same level with their commercial brethren. But dang… why must they be
so much for non-commercial use.
I'm not even saying that the software isn't worth the money, I'm just saying I can't rationalize it and I'm sure I'm not the only home researcher who would be willing to pay some reasonable amount for such a tool. Sadly, all 3 companies above have decided it wouldn't be in their interest to market to this niche.
Update 2009-12-11: Since this was written I have found that both Wolfram Research and Maplesoft offer inexpensive home versions of their products for those who are not using them in any commercial way. Mathematica is available for $300 and Maple for $240. (In order to find that figure from Mapplesoft, I had to email them directly to ask if such a thing existed, since their website is completely silent about it.)
