The pair of (desktop icon) image files Maple12Classic.png and Maple12.png could more sensibly be installed in some location such as the $MAPLE/etc directory.

Having them get installed, as in Maple 12, to $MAPLE/bin is a little strange.

The usual use of bin directories is for executables, and not binaries in general. Eg. some other binary objects such as shared object libraries may be in lib/, and text shell-scripts may also be in bin/. So the fact thet .png files are "binary" isn't any good reason to place them in bin/.

It would be nicer if the nprofile commandline utility had its own script in $MAPLE/bin similar to the maple and xmaple scripts.

That is the place that one usually either looks for Maple executables or appends to one's PATH. A single location makes more sense and is easier.

It would also be nicer if nprofile help-page mentioned something like the exprofile help-page's comment that, "The preferred method for creating the output  file is with writeto() and/or appendto()."

Does Maple 11 support multithreading on an Intel Macintosh? You may infer from the question that I tried but was unsuccesful. I used one of the simple examples in the Threads:Create help page. I got: Error, (in Threads:-Create) No support for multithreading in this kernel This is Maple 11.02, build 330022. I am running OS X 10.4.11 on a MacPro with 2 x 2.66 GHz Dual-Core Intel Xeon processors.

OK, this time I'm really stymied.   It appears that Maple doesn't follow the same rules of operator precedence when it comes to logical operators.  p &and q &or r should be the same as r &or p &and q, but it isn't.  What gives, and how can I remedy it?

Sometimes I have to write a Maple code compatible to several versions of Maple (typically 9.5 and 10 but sometimes also 11 or VR4) and I am missing a information in Maple help pages - a changelog or, more specifically, a version information. At least, for every particular fuction or package, I am missing the information since which version of Maple it exists (eventually since which version it is obsolete).

`&*`:=1:
f:=(a,b)-> a &* b:
plots[densityplot](f,0..1,0..1,
    colorstyle=HUE, axes=boxed, style=patchnogrid);

gives the same plot as

plots[densityplot](`*`,0..1,0..1,
    colorstyle=HUE, axes=boxed, style=patchnogrid);

The ampersand is ignored!

It is interesting that replacing f with f[1] produces a plot that it should produce. This works reverse to the evalf bug - works OK indexed, and not OK - not indexed.

I suggest adding descriptions of variable, size, and factors() to the GF help page. Currently, they are not even mentioned there.

Based on a problem / bug with 'fibonacci', which Plouffe states in the symbolic newsgroup, I isolated from his example a situation, where elementary operations on lrage interger sends Maple to death on WIN (but seems to work on a MAC).

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.

I am missing the F1-help to work properly after highlighting words
at least for the following

invfourier ---> completely missing (it is in inttrans)
invlaplace ---> completely missing
invmellin  ---> completely missing
fourier    ---> MTM[fourier], but not inttrans

Parts      ---> completely missing (expect it in IntegrationTools)
Flip       ---> ImageTools[Flip], but not...

1) I would like to see the possbility of color-coding the assumed variables (insteas of the ~ postfix or a text). Expressions with a lot of ~ are soon illegible, and anyway cannot be easily published. Color seems an obvious possibility.

2) I would also like to see an "execute worksheet up to cursor" option. This would be useful to test modifications of long worksheets, where performing a manual selection is cumbersome. Such an option is common in debuggers, for instance.

I recently discovered a minor variation on the technique of building a set using a table. The purpose for using a table rather than inserting new items directly into a set is that, in a loop, the latter technique is O(n) rather than O(n).  The way I would normally do this is to assign a counter and an empty table, and then, in a loop, compute the new element, increment the counter, and insert the element into the table at the counter index.  For example,

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,

It's not often that a funny music video is made about Fractals. Here is something very special:
