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.

I suggest using spell checker on the help pages.

For example, such thing as

Other commands, such as MTM[vertcat], offer new functionality: vercat provides an easy way to combine arrays.

with both vercat and vertcat in the same sentence in the ?MTM help page should be easily caught.

Reading Alejandro Jakubi's Saving Results article, I got interested in new ExcelTools package.

First surprise - it doesn't work from Classic, works only from Standard Interface (that was mentioned in the help pages.) Well, I started Standard Maple and did the example from the help page,

solve(piecewise(Or(x=1,x=2),1,0)=1);

                       {x = 1}, {x = 2, x <> 1}

The expected answer is 1, 2. That would be consistent with

solve(piecewise(Or(x=1),1,0)=1);

                                  1

solve(piecewise(x=1,1,0)=1);

                                  1

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

                                false

I couldn't find any value giving true.

Not talking about giving wrong answer (as, for example, in A110375 thread), many Maple comands are amazingly inefficient. For example, SearchAll from ListTools pakage,

time(ListTools:-SearchAll(2,['$1..1000'$1000]));

                                33.977

Compare it, say, with the following obvious way of doing that:
