Just a small issue with how you insert a ^ (caret, wedge, circumflex, arrow, hat, what have you), / (forward slash), or * (star, asterisk) as a literal in a comment in Maple.

In regular code, it works fine;

Typing \_ produces _
Typing \^ produces ^
Typing \/ produces /
Typing \* produces *

In a comment, only underscores work as expected.  The caret, asterisk and slash leave behind the escaping backslash, which you will have to go back and delete yourself.

In previous version  "e" was recognised as the constant.. Now, it is needed to write in special way to get

the digits of "e" ( to use "expression palette")

I really do not know if that is a progress or regression for Maple.

External calling functions from Windows dlls in Maple uses __stdcall calling convention.

Most Windows dlls including <windows.h> are using that convention (called also WINAPI). However, C runtime dll (msvcrt.dll) and most mathematical dlls - such as gsl, PARI, etc. which would be very useful, are using __cdecl calling convention and functions from them can not be easily called from Maple. One has to create a wrapper dll with __stdcall calling convention for that. In particular, Axel Vogt did that for a part of PARI.

Would that be possible for Maplesoft developers to add option CDECL in define_external in Maple 15 allowing calling C library functions and functions from gsl, PARI, etc. directly from Maple, without a burden of writing __stdcall wrappers for them first?

 Here is a example of a cesaro sum used when a series fails to converge in the usual sense of a sum.

sum((-1)^n*(n^(1/n)-a), n = 1 .. infinity) has a cesaro sum of 1/2*(a+2MRB constant-1).

Proof:

We are given that                            S=  sum((-1)^n*(n^(1/n)-a), n = 1 .. infinity) .

Expanding the infinite series we get         S=(a-1)+(2^(1/2)-a)+(a-3^(1/3))+(4^(1/4)-a)+... .

Collecting the a's and the surds we see that S=a-a+a-a+...+(-1+2^(1/2)-3^(1/3)+4^(1/4)...) .

By Grandi's series  we know that             S=1/2*a+(-1+2^(1/2)-3^(1/3)+4^(1/4)...) .

Collecting the infinite series we get        S=1/2*a+ sum((-1)^n*(n^(1/n)), n = 1 .. infinity).

Which can be shown to be                     S=1/2*a+ sum((-1)^n*(n^(1/n)-1), n = 1 .. infinity)-1/2 .

Thus, by factoring out the 1/2, we get           S=1/2*(a+2 sum((-1)^n*(n^(1/n)-1), n = 1 .. infinity)-1) .

Therefore,                                   S=1/2*(a+2MRB constant-1) .

In order to give symbolic results for that familly of sums Maple shouldmake this identify an integral part of maple in future versions!

Original investigator of the MRB constant.

Quite often, when plotting an expression in involving trigonometric functions applied to (a rational polynomial of) the main variable, it is desirable to have the major ticks along the x-axis be labeled by multiples of Pi. In particular, it can be much more appealing to have those tickmarks be labeled with short rationals multiplied by the 2D Math symbol π.

An example of the magic of java. It has an excellent widget toolkit too! Study the beautiful image below for an example of what it can accomplish.

When selecting Plot > Plot Builder > Options the gui hanged like this with no way to restore the program, the x buttons had no effect, and no other input had an effect. I was left to close the process and lose my changes to the .mw file. It's running on XP 64-bit.

It is already September and there has been no updates for the latest Maple release.  Am I to expect that when I purchase the newest copy of Maple that what I buy is what I get and there maybe no updates?  I mean Maple 10 was on the market for a full 2 years with updates, 6 to be exact, so users must have pretty satisfied with the service, hopefully.  And Maple 11 users had their version on the market 3 months longer than Maple 12 although from...

My goal is to make maple better so here I am going to point
out another annoying thing in Maple. If you for example want to have
two plots side by side (I know your question is about two plots in the
same chart but I still think is relevant) in an array then such a array becomes very hard to delete.

A:=Aray(1..2):

A[1]:=plot(....)
A[2]:=plot(...):

display(A);

plot1    plot2


Now the Array A...

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?

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...

Currently, using Explore results in a new worksheet which contains all the sliders and output components.

And there is code, which makes it all "work", that gets hidden in that new worksheet. But It's very awkward to copy those Components back to the original worksheet, because of the disassociation with the working code.

If, instead of having dependent code be hidden in that new worksheet in collapsed Document blocks, all the working code were instead inlined...

I would like to translate Maple's products into Russian and to help russian users in Maple's education.

I am using Maple 14 in Windows xp.

If you enter an equation, or expression into a table the screen display shows more than adequate amount of blank space remaining in that particular table row.  However, when you look at the document in print preview or after printing it out you find that the free space in the row is not correctly displayed.  This is by no means subtle.  For example, I enter an equation into a table and it looks like at...

I sometimes like to use Maple help online as it allows for enlargement of font size very easily.  However, there is no text wrapping and makes reading difficult.
