I only have Maple 2025.2 on this new PC. Could someone just run this code on earlier Maple version and see if they get same crash?

I am finding many crashes in Maple 2025.2 (3 so far) and I am only 25% in my test. But not sure if this is new or was there in Maple 2025.1 or earlier.

I am trying to document all the new problems in Maple 2025.2.

Here is the worksheet (save all your work just in case).

I also checked if libname had PHYSICS on it but no SUPPORT tools, and the crash also goes away. So the bug seems to be when adding SUPPORT tools.

How to make plottols:-exportplot work in cmaple.ex...

Asked by: nm 11558

Yesterday at 4:32 PM

2 7

Using Maple 2025.2, I need to run my test in command line (for other reasons).

Only problem is that plottools:-exportplot does not work as well as in the GUI. The gridlines do not show.

I reported this to Maplesoft years ago. Was hoping may be it is fixed in Maple 2025.2 but it does not seem to be.

Anyone knows of a trick to show gridlines in plot (2D) when using cmaple.exe?

Here is example. Started cmaple.exe from command line (which on windows is

c:/Program Files/Maple 2025/bin.X86_64_WINDOWS/cmaple.exe

> p:=plot(x^3, x = -8 .. 8, color = "blue",axis=[gridlines=[10,color="red"]]):
> plottools:-exportplot("filename2.png",p);

You might want to use setdirectory() to some folder such as c:\tmp to save the plot to.

But the plot is missing the gridlines

In the UI it looks like this

This is really a big problem for me. I have to run the program in command line, but the plots geneated from command line do not look as good as when running the same program in maplew.exe vs. cmaple.exe.

This is a problem in Maple for years and years and no one in Maplesoft seems to care to fix it.

So I am asking hoping someone will have a trick to make gridline show using cmaple.exe.

Updated

I just found the case number. Actually I only reported this to Maplesoft 6 months ago. I thought it was longer than this.

Maybe they will fix it in Maple 2026?

I know Maplesoft is very busy with A.I. stuff these days, but hopefully someone will be able to have 1-2 hrs spare time from AI work and look at this and fix it.

It should not be hard to fix I would imagine, since code works in worksheet so someone just needs to use /copy same code that works in worksheet and make sure it works in cmaple.exe

Hello,

Thank you for contacting Maplesoft.

I have forwarded this inquiry to our Math Team / R&D Team. Once they review the situation and provide any further updates and/or insights, we will contact you. Thank you for your patience.

Subject: exporting plot using command line maple 2025 losses gridlines.

When I export a plot to postscript using command line Maple 2025,
the generated plot is missing gridlines.

Same exact code executed inside GUI Maple 2025 shows the grid lines
as expected.

What to do to obtain same plot from command line Maple as from
the GUI?

I am using Linux Arch based distribution with Maple 2025 linux.

Here is the command I used

/home/me/maple2025/bin/maple A.mpl

Here is A.mpl

----------------------
p:=plot(25*t^2+10*t+20,
axes=boxed,
labels=[t,x(t)],
axis=[gridlines=[color=lightblue]],
'color' = 'red'):

plotsetup(ps, plotoutput="p.ps",plotoptions=`color,noborder`);
print(p);
------------------------

If you run the above, you will see p.ps file generated.
But looking at the plot inside it, shows no gridlines.

Could this be fixed or do I need different options to
make gridlines show running command line Maple?

How to install Physics updates package in Maple 20...

Asked by: nm 11558

November 24 2025

1 1

I am trying to see if installing Physics update package will fix a problem I am having as described here by having a fix that maybe not included in Maple 2025.2

But I do not know how to do that. When doing Physics:-Version(); or Physics:-Version(latest); Maple says

`The "Physics Updates" package is not available for the version of Maple under development`

Does this mean Physics update package is not needed in Maple 2025.2? Otherwise, what are the instructions to install Physics package now?

May be someone could clarify the status of Physics package and if it is something that one should still install along with SupportTools which in Maple 2025.2 was there automatically and did not need to install it.

Update

JUst verified that Physics update package V 1881 is still needed in Maple 2025.2 as it has important fixes not merged in Maple 2025.2.

To install Physics package in Maple 2025.2 had to click on the top right corner of the worksheet (the down arrow) near the "sign in".

Then go down to "packages" and select and click on the install button next to Physics package. (first in list).

This will download and install it.

Now closed all of Maple and restarted it.

Now Physics package V 1881 is installed and have fixes in it that are missing from Maple 2025.2. This is why my test was failing. Now the test do not fail.

So first time, the command Physics:-Version(latest) does not work. But from now on it should work.

I would have expected all fixes made in Physics update to have been merged into the new Maple release.

What can cause Physics to be activated when one is...

In 2025.2, I found that calling Physics:-Setup causes code of `convert/diff` to change (on the fly) causing error.

I removed from my code the places I was calling Physics:-Setup explicitly, but the error still shows up. Which means there is still places in the code to cause Physics to come into play.

I just installed 2025.2 and have not done anything yet. Just running a test.

Does one need to install Physics package?

First, let me give an example showing that calling Physics:-Setup changes `convert/diff` which ends up causing an internal Maple error

Original result. No problem

Error, (in unknown) invalid input: diff received infinity, which is not valid for its 2nd argument

Download why_code_changes_calling_Physics_maple_2025_2_nov_24_2025.mw

Notice that now calling PDEtools:-difforder(convert(T,diff)) fail because Physics:- was called.

But my code now has no calls to Physics:-, I made sure to comment all those out.

But I still get same error when I run my test program. Not able to find where Physics is "activated" again to cause the code change in `convert/diff` that happens dynamically when Physics is loaded.

It must be happining on different call internally. But have no idea why and where.

This is all on new PC. I have no Maple ini files or anything like this that can cause this.

Will installing Physics package explicity fixes this?

Update

I think I know why this happens. Not all fixes made by Edgardo S. Cheb-Terrab in last Physics update are included in Maple 2025.2 !

See https://mapleprimes.com/questions/240843-Why-PDEtoolsSolve-Fail-On-This-Equation where fix is made in Physics v.1880 which I confirmed in Maple 2025.1.

But now I checked and this problem is back in Maple 2025.2. which means that fix was not merged into Maple 2025.2. How could this happen?

Download fixed_in_2025_1_but_missing_in_2025_2.mw

So I am hoping that figuring how to install Physics update in Maple 2025.2 will fix the current problem with convert and also bring that old fix for PDEtools:-Solve back into Maple 2025.2.

This is something that Maplesoft should have taken care of.

Update

Figured how install Physics update package V 1881 and doing so fixed this problem in Maple 2025.2 !

This tells me that all fixes that were in Physics update package were not merged into Maple 2025.2

This worksheet shows that now code works OK, but need to make sure to install Physics update package in Maple 2025.2

Hidden execution group boundaries...

Asked by: vv 14077

November 24 2025

1 0

The new default in Maple 2025 is to hide the Execution Group Boundaries in Worksheet mode.
In order to make them visible one has to use the menu

View > Show/Hide Contents > Execution Group Boundaries F9

or to press the F9 key.

The question: is there a method to have again visible boundaries by default?

(Hiding the boundaries does not seem to be a good idea because an execution group can have (it is not clear why!) multiple prompts.)

MapleToolbox 2025.2 with Matlab 2025b ...

Asked by: MichalKvasnicka 229

November 19 2025

Is it possible to install and operate Maple toolbox 2025.2 with MATLAB R2025b on Linux (Ubuntu 24.04) platform?

On Ubuntu 24.04 installation process hangs after location of Maple and Matlab folders at installer window.

Any idea what is wrong?

Of course, I know that actual Maple 2025 system requirements mention support only for MATLAB R2024b, but this is an obsolete version of MATLAB.

And finally, Is there any reliable and effective way how to switch between Maple and MATLAB symbolic engine?

Elliptic curves...

Asked by: Alfred_F 435

November 16 2025

2 7

Having started learning Maple about a year ago as a beginner, and now having mastered my preferred area of "ordinary differential equations" fairly independently, I'd like to explore "elliptic curves" in Maple. For practice, I've chosen two problems, for each of which I only know one solution:

y^2 = x^3 -51*x^2 + 867*x - 4792 (17;11)

y^2 - 2*y + 14 = 2*x^3 + 11*x^2 - 29*x - 17 (3;7)

My attempts using commands like "algcurves", "ThueSolve", and "parametrization" have failed. How does one approach such problems in Maple? I'm also particularly interested in the group-theoretically based graphical secant method.

(I'm familiar with the book by Silverman/Tate.)

How to delete this interactive plot builder call...

Asked by: C_R 3537

November 10 2025

In the attached document (an excerpt from a larger document) is a call to the interactive plotbuilder.
The call is somewhere hidden in a document block but the document block with the redline is empty. Deleting the document block only moves the red line to another block.

Executing the entire document (with !!!) starts the plot builder, execution step by step (with !) does not.

How to delete the call to the plotbuilder?

I am working in Maple 2025:

I executed the following code:

Maple replied with:

(x^2 + 2)^2/4

I was expecting :

x^4/4+x^2

Did Maple do this integration incorrectly?
