Well, if it is known, wouldn't it have sence to at least mention about that on the help page, together with the fact that the default option is color now?

Alec

Testing? Isn't that what customers are for?

Personally, I prefer BSD type licensing, too. As well as many other people in academia.

For math software, people usually choose GPL specifically to prevent including their work in commercial CASs.

Actually, what I thought about that - Maple could use it in its own interests - it could become GPLed itself, include all free GPLed software, and still continue being commercial. If there were many useful GPLed packages, that would make sense - that would give it an advantage comparing to other CAS (the same advantage that SAGE has now, being GPLed.)

PS After reading that, I realized that I am following Mehran Basti more and more. I already give advices to Maple owners and executives. The next step, probably, would be to start giving advices to Canadian goverment, and then, gradually, I might rise to advising Vatican and Turkey. -Alec

With color=grey, the axes, with tickmarks and numbers, still were white in the previous (parabola) plot - i.e. it was just a parabola without axes and with a hole in it at 0. Does it work in 3D plots the same, if axes are specified?

Alec

Acer,

For some reason, I thought that it was LGPL. It is BSD - wow, that's much better! Great that you mentioned that.

Thinking that it was LGPL, I didn't use it in one of my recent projects. I should have checked that. Now I'll get some improvements there (I hope.)

If I recall correctly, both Mathematica and SAGE just didn't display zero at all in this plot. Also, both of them (as well as Matlab) drew the parabola in blue color.

I was actually quite surprised looking at the eps output in Standard. It was much better quality. The parabola was red and this seems to be not mentioned in the help pages, but the line widths and zero position were much better. Is it only in Windows, or in Linux, too?

Alec

So, much of Maple performance is obtained by using Free software, GMP and ATLAS?

What would happen if they changed their licensing from LGPL to GPL?

Just tried it in Standard. The output actually looks OK, better than in Classic. The parabola is red instead of black and white output in Classic. 0 is located properly. No DSC errors (%%Pages doesn't match %%Page in Classic.) The file size is 48.7 KB instead of 6.03 KB in classic.

2 bugs with color.

Adding color=none to the plotsetup produces black background, white axes, and parabola is not visible.

Adding color=grey instead produces a plot without axes and with a hole in the place where parabola intersects with axes.

In both cases, the size of the output is about the same, 48.7 KB.

Alec

Here is another one with black background, but obtained by plotting to PostScript device in Standard Maple,

plotsetup('ps', 'plotoutput' = "plotBW.ps", 
    'plotoptions' = "color=none,portrait,noborder"); 
plot(x^2, x = -1 .. 2);

Elementary functions are also very good there. In particular, both exp and ln, as well as trigonometric functions, are much faster and with only slight loss of precision comparing to the OS (or C runtime library) functions.

Intel has a very good math library. I hope that it is used in Windows, Mac OS X and Linux for evalhf.
