I received my Ph.D. from the University of Pennsylvania in 1998 and I have been teaching since then at SUNY Oneonta for 1 year, at Shepherd University for 5 years, at Tennessee Tech for 2 years, at Lane College for 1 year, and this year I taught at the University of Massachusetts Lowell. My research interests include Representation Theory and Combinatorics.

If you want help, you should try to make your code usable from Maple. As you said - converting Mma code to Maple is painful and takes long time. I personally have very limited amount of time that I can contribute here, and other people who could help, probably, too. Also, I don't download worksheets from here (for several reasons including security)

Another option is to email to support@maplesoft.com and ask them for help. I don't know any cases when that was helpful though, but that doesn't mean that such cases don't exist.

Beside the idea of logging in, I also don't like the phrasing - "Maplesoft member" - if it was "Maplesoft Application Center member", it would sound better.

Some time ago (I don't know the situation at present time), there was a link there to subscribe to the newsletter, but there were no a link to unsubscribe from it (that is illegal at least in the US). I had to email to various (4 or 5) email addresses until I was finally unsubscribed. Still, I continue receiving some marketing stuff from Maplesoft from time to time. Fortunately, I use mail filtering and it goes immediately to junk mail, so I've noticed that only looking through the junk mail before deleting it.

That easily can be done with many other graphics packages. Matplotlib, for example (SAGE is using it.)  Or Asymptote.

I also think that it shouldn't work, but it works for RealRanges,

is (RealRange(1,2) in RealRange(0,3));

                                 true

Also,

RealRange(5,5);
                                  5

gives a number 5 and not a set {5} as it should, and

RealRange(1,0);
                              BottomProp

which would have sense if it was named more appropriately - as EmptySet, for example.

Congratulations, Mario!

You beat a lot of people in this competition - Mariner, roman_pearce, ..., DJ Clayworth, pchin, Dave L, and jpmay (in points order).

However,

is(ComplexRange(0,2+2*I),type);

                                 true

is(CompexRange(0,2+2*I),property);

                                 true

is(ComplexRange(1,2+I) in ComplexRange(0,2+2*I));

                                 FAIL

is(RealRange(0,2) in ComplexRange(0,2+2*I));

                                 FAIL

If all that "works as designed", I wonder how this "more than a program" is supposed to be used.

Perhaps, I didn't understand the question, but it gives something different with x instead of z,

dd:= PDEtools[dpolyform](y(x)=f,no_Fn);

Would it be possible to give Maple Mentor Award winners additional editing privileges - such as an ability to edit own posts after somebody (including yourself) replied to them?

Is there a multiplication (or other) sign in front of the last diff?

I've just added macros for maple (red and bold) input, mi - with a prompt, and
mn - without a prompt. They were suggested by Alejandro Jakubi.

They can be used as

<<mi(some maple input)>>

and

<<mn(some maple input>>

Please feel free to experiment with them on their test page, MiTest.

I used them already in SearchAll.

I meant inplace there, but inline seemed to work well, too - the time measurements with it were consistently smaller. The source code for map is not available, but it seems as if everything entered in square brackets after it gets transferred to the corresponding option, so inplace becomes opton inplace and inline becomes option inline.
