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.

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.

The Maplesoft Physics Updates, introduced over a decade ago, brought with them an innovative concept: to deliver fixes and new developments continuously, as soon as they enter the development version of the Maple library for the next release. A key aspect of this initiative was prioritizing the resolution of issues reported on MaplePrimes, ensuring that fixes became available to everyone within 24 to 48 hours. Initially focused solely on the Physics package, the scope of the updates quickly expanded to include other parts of the Maple library and the Typesetting system.

This initiative, which I developed outside regular work hours, aimed to enhance the Maple experience—where issues encountered in daily use could be resolved almost immediately, minimizing disruptions and benefiting the entire user community through shared updates.

As of January 1st, I have stepped away from my role at Maplesoft and have been increasingly involved in activities unrelated to Maple. This raises the question of what will happen with the Physics Updates for Maple 2025 and after.

The Physics project remains a unique and personally meaningful endeavor for me. So, for now, I will continue to dedicate some time to these Updates—but only for the Physics package, not for other parts of the library. As before, these fixes and developments will be included in the Physics Updates only after they have been integrated into the development version of Maple’s official library for the next release. In that sense, they will continue to be Maplesoft updates.

On that note, the first release of the Physics Updates for Maple 2025—focused solely on the Physics package—went out today as version 1854. To install it, the first time open Maple 2025 and use the Maplecloud toolbar -> Packages, or else input PackageTools:-Install(5137472255164416). Any next time, just enter Physics:-Version(latest)

As for fixes beyond the Physics package, I understand that Maplesoft is exploring the possibility of offering something similar to what was previously delivered through the Maplesoft Physics Updates.

All the best

PS: to install the last version of the Maplesoft Physics Updates for Maple 2024, open Maple and input Physics:-Version(1852), not 1853.

I was reading a book on complex analysis, and I tried to answer some questions like "Find and plot the sixth roots of unity on Maple."  I tried the following code, which works. Is there any other way to solve and plot the same question?

Hello everyone,

I want to plot some 2D polygon shapes in one plot. Every shape should have their own color. 
for example: from the Plasma colorschem "Plasma 212" 

Can somebody give me an example code ?

Thanks

Hello,

I have several sets of nonlinear equations that need to be solved for certain unknowns. In many cases, the equations admit more than one solution, and Maple is sometimes able to find different solutions by changing the order of the unknowns.

However, in one particular case, I haven't been able to get Maple to find a known solution that was obtained elsewhere.

Below are the equations, the list of unknowns, the solution returned by Maple, and the alternative solution I'm trying to obtain.

Is there a way to guide Maple to find this other solution?

How does one create a new section using UI in Maple 2025?

I've done this many times in Maple 2024. To make section there, I simply do
   Insert -> Section

But I am not able to find this using the UI in Maple 2025, under insert 

Ofcourse, I know I can add section using

                    CTRL .

which works. But I was wondering, where is insert section is in the GUI? Hard to find. I do not see anything called section in the menu there., I tried few of the other items, but so far, can't find section.

Is it possible to reduce icon shaps in the top bar in Maple 2025 UI? It takes too much vertical space

Here is how Maple 2024 UI look in worksheet mode:

Compare to same thing in Maple 2025, worksheet mode

Comparing just the top bars, we see 2025 is much large and takes too much space.

We see Maple 2025 takes about twice as much vertical space as Maple 2024 from top of window to the first > in the worksheet.

Is it possible to have top bar in Maple 2025 with small icons or minimized somehow?

I also find the blank gray line annoying above the |> in Maple 2025 and I have no idea what it is there.

Over all, I like Maple 2024 UI much more. Easier to look at on the eye for me. The dark gray background is annoying for me to look at.

My screen changed resolution and now the maximize and minimize controls are cut of. (Also the task bar is gone.) Are there any Windows short cuts to maximize or minimize? Alt-F4, which closes the window, works.

Again, and again ... after all upgrades of Maple there is always delay of available Physics package compatible with latest version of Maple... :(

I am trying a trial version of Maple 2025 on Linux, since not able to use Maple 2025 on windows (uninstalled it).

Everything was working well, (no UI shuffling at all so far) except now I find I am not able to export plot to PostScript. 

Same code works fine using cmaple.exe on windows. But using cmaple on Linux, it fails.

How does one export a plot using Maple 2025 on linux to PostScript, and it must be using cmaple, since I run everything from command line.

I also made sure I have /home/me/maple2025 and /home/me/maple2025/bin.X86_64_LINUX
 in my Linux $PATH. 

Here is a MW

# A.mpl file

    p:=plot(sin(x),x=-3..3):
    plotsetup(ps, plotoutput="p.ps");
    try
        print(p); 
    catch:        
        plotsetup(default):   
        print(lastexception);
    end try;     

   exit();

I run the above using the command

>/home/me/maple2025/bin.X86_64_LINUX/cmaple A.mpl

The problem seems to be due to cannot locate postscript AFM files which I've seen this before and was never been able to get any help on it. I asked about this missing AFM files here many years ago, but can't find the question now searching and no one from Maplesoft seems to know why this happens.

Same exact code works fine on windows under DOS using cmaple.exe.

Any one knows any workaround? I looked at export command but it does not support PostScript.

Without being able to export plots from command line, I can't use Maple 2025 on Linux. So I hope there is a work around. Are these AFM files supposed to come with Maple? Maybe I need to set some path to help Maple find them?

When I google this, it says

So maybe Maple does not ship with AFM files like it does with windows and mac? Where do I get these from and where do I put them on Linux? Why Maplesoft does not mention anything about this in installation instructions for Linux?

Could someone with Maple 2025 on Linux try the above and see if it works for them?

Update

so far, jpeg export works only

But can't use jpeg. need ps.

I also copied Maple afm/ to /usr/share/fonts and refreshed font config using fc-cache -fv , and Maple still does not find the AFM font files.  So I have no idea how to make Maple find its own afm/ folder.
