This post had a centered H2 header that appeared fine in the wysiwyg post editor during composition but is absent in the Preview or actual Post (in my firefox 3.6.6).

It appeared in the source view, during composition in the editor, like this,

<h2 style="text-align: center;">This my header.</h2>

I tried it also in an earlier submission, with the same result. When I attempt to re-edit that comment, the header was then missing in the source view as well as the posted view.

Could it be, that the submission step causes some html content to vanish?

The Maple ?Compiler can compile a limited subset of Maple commands to native code. The result is substantially faster than running interpreted Maple code. This article shows how you can save a compiled procedure for reuse.

When a Maple procedure is compiled, a shared object library (dynamic-linked library for Windows) is created on the file system, as a temporary file.  When the Maple...

If you search for a phrase which matches (fully or partially) the title of a post A, then the search results will contain every other post which the search engine recorded while post A was listed in the right panel.

In other words, the search engine recorder is picking up  the right panel (latest titles, per forum) displayed while viewing other unrelated pages. So lots of other pages get inappropriately connected to all the keywords or phrases in those latest titles.

The Linear Algebra package seems only able to handle Vector and Matrix algebra when the dimensions are given specifically.

It would be very helpful if the package were to be extended to cope with the situation where some or all of the dimentions were given symbollically. Of course, assume could be used to indicate when two dimensions were equal.

Are there any plans in this direction for future releases of Maple?

I had started to create a procedure for finding the centroid of a list of points.

Centroid := proc (list)
local a, centroid, x, y, i:
a := nops(list):
x := 0:
yi := 0:
for i from 1 to a do
x := x+list[i, 1]:
y := y+list[i, 2]:
end do:
print(`Centroid is at`,([xi, yi]/a)):
end proc:

But I thought there needs to be something simpler than that.  And here we are.

Centroid2 := proc (list)
local i:
print(`Centroid is at`, add(i, i = list...

Happy Dominion Day.

Having Maple 12 I try to use concurrent gfun version 3.52 and have problems
to run an example (from a lecture):

libname:= "D:\\_Work\\Maple_Work\\z_Packages\\gfun", libname; # my setting

with(gfun) : gfun:-version();
with(NumGfun) :
                                 3.52

  restart; interface(version); Digits:=14;

  f:= x -> (x+1)^(x+1);
  simplify(int(f(x),x)): 
  F:=unapply(%,x);

The term “from months to days” is a favorite slogan of mine and I have relied on it religiously for over two decades to illustrate the fundamental benefit of symbolic computation. Whether it’s the efficient development of complex physical models using MapleSim, or exploration of parametric design surface equations (my dissertation) using good old fashioned Maple V Release 2, the punch that symbolic computation provided was to automate the algebraic mechanics...

The final SCR dropdown menu, showing the choice of versioned products against which the Softwware Change Request is submitted, doesn't yet (06/29/2010) include Maple 14.

An improvement which would make many applications involving Components a lot better would be if an "image" were a first-class object in Maple. That is to say, if an image object could be used in Components without having to refer to an external file.

It's a big weakness in Maple's functionality, that things like the following don't work.

bar:=ImageTools:-Create(...);

DocumentTools:-SetProperty(Label0,image,bar);

The above is just an...

The Popular Post and Popular Question badges require 1000 different people to view the Post or Question. A number of Posts and Questions show that they have over 1000 views, but their creators haven't received the badge. This is because the count currently displayed includes all views of the page, including repeats from the same Member or IP address.

I just published an update that now allows you to hover over the view counter and have the number of unique viewers appear in a tooltip. This should be useful for people curious to see how close they are to earning those two badges.

Christopher2222's recent post reminded me of a new plot feature that inadvertently (and through my own fault) got left out of the new-features help pages. The 'filled' option now takes a true/false value or a list of suboptions. The suboptions apply to the polygons that make up the filled region under the curve.

plot(x^2, x=0..1, color="NavyBlue", thickness=3, filled=[color="Blue", transparency=0.7]);
