In the File menu,  the Export As dialog is missing. Only the default (.pdf) can be used; no .mpl or .tex)
The Save As dialog is incomplete (e.g. save to .mws).

Or, is the installation corrupted?

In the transformation w = e^z, vertical lines in the complex z-plane of the form Re(z)=a are mapped to circles of radius e^a in the w-plane.

Can I create a Maple visualization that does the following:

  1. Displays the result side by side, showing each vertical line in the z-plane and its corresponding mapped circle in the w-plane.

  2. Does it use a different color and style for each line and its image (e.g., dashed, dotted, solid, or different colors)?

I need to take up an issue which is quite old, but still unsolved.

https://www.mapleprimes.com/questions/234249-Text-Quality-On-Screen

The problem is that in specific display configurations with one (rotated) vertical screen and multiple horizontal screens, the quality of fonts especially is significantly lower in Maple as with a configuration with just horizontal screens.

The affect is visible in Maple when it is on the horizontal (unrotated) screens.

Here are screenshots for comparision, and the layout of my desktop.

Screen layout:

Screenshot rotated

Screenshot unrotated

It seems that the problem is present when starting Maple. Changing the rotation of the screen when Maple is running does not affect the font quality in Maple.

Other (Windows) programs are not affected at all of this changes, so this seems to be a Java issue.

With the new GUI:
I get all files (*.*) listed by default.
Other file types to filter are not listed.

Is this the same on other machines?

Can I do something about it?

I'm struggling to find the Undo botton, according to the help file they should reside under "View" menu - select Toolbar.

I can't find any "Toolbar" in the View menu.

How do I make indents in Maple 2025 for more readable layout?

Haven't used that much in 2024, but according to help this should be in Format - Tab settings. I don't find that in 2025 unfortunately.

I know of 3 ways to remove RootOf, but sometimes they give different result. How does one decide which to use? This is done in code. So method to decide can't depend on looking at the screen and see which result one "likes" more than the other.

Is allvalues() the one to use all the time? Could one of these 3 methods fail, and then one has to try the next one?

I am studying the Julia sets. I have tried the following two codes to generate Julia Sets. The first one I found in Maple Help, and the second one from http://ftp.informatik.rwth-aachen.de/maple/mfrjulfn.htm. I am wondering if there exists another code to generate the Julia set. My question is just for educational purposes, because those two codes work fine.

I teach math at the high school level.

I am worried that Maple 2025 appears to be slower than Maple 2024 - in particular for students with older, less strong laptops.

Maple 2025 takes 50% longer to start than Maple 2024 (or Maple 2025 Screen Reader which I expect to be using).

So, on more sluggist student laptops I fear the slowness overall will be an issue - in particular as Maple regularly has to be shutdown and restarted for some of those students.

Further, I really miss the "recompute section !" and the "magniffy" icons on the quest access bar. Having "recompute entire worksheet !!!" seems unwise though. I wish you could costumize the quest access bar.

Overall, from a teaching point of view, I am not at all impressed, sadly.

Hello,

Is there a special command in Maple (whatever the version) which returns all functions available?

ex: ?*sol* which at least will return solve,dsolve etc.

Thank you and kind regards to everyone.

I'm updating to Maple 2025. Are there any feature differences between Linux and Windows versions?

Thanks.

Just an observation.

I was wondering if less obvious errors than in the below can be avoided with future versions of the AI assistant. Maybe a warning that a formula uses special Maple symbols is possible.

Formulas without dimensions are more susceptible to undetected errors.

Deflection of a circular cantilever

(a first attemp with the AI formula assistant)

_local(I)

I

(1)

AI prompt: Deflection of a circular cantilever with a  force applied at the end

Correct formular inserted ->
delta = F*L^3/(3*E*I)

delta = (1/3)*F*L^3/(E*I)

(2)

AI prompt:  Moment of inertia of a circular cross-section

Correct formular inserted ->

I = (1/4)*Pi*R^4

I = (1/4)*Pi*R^4

(3)

subs(I = (1/4)*Pi*R^4, delta = (1/3)*F*L^3/(E*I))

delta = (4/3)*F*L^3/(E*Pi*R^4)

(4)

params := R = 25*Unit('mm'), F = 200*Unit('N'), L = 1.*Unit('m'), E = 210000*Unit('N'/'mm'^2)

R = 25*Units:-Unit(mm), F = 200*Units:-Unit(N), L = 1.*Units:-Unit(m), E = 210000*Units:-Unit(N/mm^2)

(5)

subs(R = 25*Units:-Unit(mm), F = 200*Units:-Unit(N), L = 1.*Units:-Unit(m), E = 210000*Units:-Unit(N/mm^2), delta = (4/3)*F*L^3/(E*Pi*R^4))

delta = 0.1034759757e-8*Units:-Unit(N)*Units:-Unit(m)^3/(Units:-Unit(N/mm^2)*Units:-Unit(mm)^4)

(6)

simplify(%)

delta = 0.1034759757e-2*Units:-Unit(m)

(7)

NULL

The dimension of m^9 for a deflection clearly indicates an error.

A better prompt to avoid this error (caused by automatic simplification) could not be found

P.S.:

This is a real example that happend to me where I did not notice the minus sign in Maples output in equation (1). The error  can easily be fixed by adding "local I" as the first statement of the document and the deflection becomes 1 mm.

Historically, when the Maple program is open and I double-click on a Maple document in my file manager (Windows), the document appears in a new tab of the open program.

With version 2025.0, I performed a completely clean install, deleting files and inheriting no properties from 2024. Now, when I repeat this process, a new window/program is created with the document appearing there. The document does not appear in another tab of the original window/program. Changing the option of sharing the same Maple math engine does not affect this unexpected behavior. 

Do others observe this behavior? Is there an option in one of the "Maple.ini" files that I could change? Or is this a bug?

I should note that this behavior is identical on multiple Windows 11 machines. The 2nd one was not a clean install. 

I have functions using define_external to call a .dll  In uploaded file "dll_test.mw" I'm showing one such function.  Immediately after defining the function I call it and it works.  There are a lot more similarly defined functions and once defined in the worksheet they are working as hoped. 

My question is can I make the functions avaliable across multiple worksheets somehow?  google ai suggested using "read" but in uploaded file "read and load test.mw" you can see that it's not working for me.  using read I get an error I don't understand and using load doesn't return an error but it also doesn't result in an executable KinAddCurveData function.

Any help would be very appreciated.
