Does Maple natively work while using a VPN? If not, where do I go to learn how to configure it so it will work using a VPN? In Maple 2025 and Maple 2026, Maple will soft-lock when when attempting to execute any worksheet or attempting to read any help section when using a VPN under the default configuration configuration of Maple. 

I'm trying to play around using Maple from other programs (Python, Grasshopper, etc.).

As far as I can see the options are cmaple.exe (command line) and OpenMaple.

Regarding OpenMaple I'm stuck with getting it to work. As far as I can see, I need to define the MAPLE variable, and extend the path, right?

I've added 2 things to the user environment variable in Windows.

MAPLE=C:\Program Files\Maple 2026
Path=.....;C:\Program Files\Maple 2026\bin.X86_64_WINDOWS

To test I've used the program provided in the help file.

import maplesoft.maple.namespace as msymbol

Unfortunately I get: ModuleNotFoundError: No module named 'maplesoft'

Any hints?

If I compare Maple 2024 and Maple 2022 on the exact same worksheet, Maple 2022 executes twice as fast as Maple 2024.

For my kind of work this is very serious. I have programs that can take 10 or more days to complete calcuations, therefore what Maple 2022 will calculate in 10 days, Maple 2024 takes 20 days. It has wasted a LOT of my time, whatever the reason is.

Here is the code: 
1) MM must be a high order series expansion with complex arguments so that simplification is not trivial. Use any such asymptotic expansion.
NOTE: I can supply an expansion for a developer through official Maple support, but cannot release it publicly as it is part of a future publication. It is easy enough for anyone to create a complex expansion, with difficult simplification.
2) The simplification of the expansion must at least take a couple of minutes at e.g. Order=10 for the comparison to make sense.
3) Then run the program for Maple 2022 and Maple 2024 respectively and note execution time.
4) This was run on Linux.

As you will see the Maple 2024 calculation takes twice as long as the Maple 2022 calculation. 
SEE RESULTS AT END OF PROGRAM.

testorder:=6;                             # Enter the expansion order here.
MM:=??:                                   # Enter the expansion here.
series(MM, x = 0, testorder):
convert(%, polynom):
map(simplify, %):
#collect(%, x, simplify):
simplify(%):

                        testorder := 6

RESULTS:

Is Maple 2026 compatible with Mac OS27.1 ___________________________________________________________

I am attaching two worksheets.  The first worksheet titled testflaw shows the original state of a module. The module in the startup code area contained two exported variables which were never implemented. The module had been used in testing the code.  The second worksheet testflaw2 shows the result after deleting the exported variables. (AsTable and TestAssociativity).  Note that when the worksheet opens a typesetting error code occurs.  It appears that the typesetting routines retain knowledge of the exported variables even after a Restart command.

On my installations I can neither convert nor copy/paste code with comments from 2D-Math to 1D without loosing the comments.
Also pasting to Word removes the comments.

Is that a known behaviour? Any workarounds?

and even correct formating ... 

but there is no possibility to correct anything, it just ignores the settings ... unfortunately, I am pushed to use an older version ...

Hope this will change.

I specifically want to install the Maple 2024 version as I am implementing a open-source research project which specifically states the requirement of Maple 2024, but in the 15 days free trial version I am not able to to so, can someone please help me!

Hi everyone,

I am experiencing what appears to be a problem with Numeric Formatting in Maple 2026.

I have a worksheet where I calculate a numerical value using evalf, for example:

evalf(1 - (3.7*90)/(10.4*3600))

which returns

0.4663461539

When I select the output and use the Context Panel → Numeric Format, for example:

  • Percent
  • 2 decimal places

the preview in the math container changes accordingly (e.g. showing something like 0.45), but the actual numerical output below still displays as

0.4663461539

Changing the number format, decimal places, scientific notation, etc. seems to have no effect on the displayed output.

Even if not using  evalf.

Is this the expected behavior in Maple 2026?

  • Does Numeric Formatting only apply to certain types of expressions or math containers?
  • Is there a known issue with formatting numerical output generated by evalf?
  • Am I missing a setting that enables formatting of worksheet output?

I have attached a screenshot illustrating the problem.

Any help or clarification would be appreciated.

Thanks!

I have a very large system of nonlinear equations in Maple 2025, and the solver takes hours. Any Suggestions?

After starting Maple

I then tried simpler prompts like "Hello", simplify(x),...

For all prompts I get the same error message.
I am not a frequent AI user but this is the first time I see that.
Has anybody else experienced the same?

Can someone send me a prompt that should work?

(Model type was Simple.)

Update:

It seems that this error occurs, when a second instance of Maple 2026.1 is started and AI is consulted in this instance. 

I'm having a strange problem in Maple 2026. When I highlight a fraction to get Maple to display it as a percentage, it leaves the fraction unchanged. Is this a problem that others have encountered as well? And what can be done about it?

1) in Mathcad there is an exponential Threshod for the entire worksheet so that a resulat like 8*10^-10 becomes 0
Is this also possible in Maple Flow 2025 ?
2) is it possible to get rid of the trailing zeros when I choose in the options the dsiplay of number format as 3 decimal digits and 1 minimum exponent digits
Thank you

I am only occasionally using Maple versions with the new ribon user interface and noticed about 2 weeks ago that I cannot interrupt for loops under these interfaces. For example this one

for i to 1000 do
    i^i;
end do

I re-run the code today (after installing windows updates) and could interrupt before the screen was filled with output but not after executing the code a second time (without restart).

Is that reproducible on other installations?

Are there other commands that cannot be interrupted? 
If that is known, are there workarounds?

Update:
I have restarted Maple and have two worksheets open with the same code. I can repeatedly interrupt in one worksheet but not in other

I notice that Maple transactions journal does not publish any new issue ever since March this year. Based on the previous recording it is supposed to publish issue each season. When is it going to promote a new issue? My research is supposed to publish there and I believe I have made some interesting progress and it is of interest to the community.
