I wonder what is the general view on this.

Maple tries hard to find analytical solutions by trying different algorithms. Which is very good. But the question is, should it also hang doing this? Should not there be a circuit breaker to prevent the hang?

I mean there must be a limited number of algorithms it tries. So at one point one would expect it will finish and return either no solution or the solution it found.

For this Abel ode   y'=x+y^3, which is known not to be solvable, Maple hangs on 

           > Step 2: calculating resultants to eliminate F and get candidates for 

I waited for almost one hour. Clearly this indicates a problem internally. Right?

There should be some internal checks to prevent this hang I would think.  I do not know where it actually hangs, since trace only shows the last step above.

It will good to find out the cause of the hang and add code to prevent this in a future version of Maple dsolve to make it more robust.

btw, using that another software, it returns instantly on this ode with no solution. May be the other software did not try as hard, but at least it did not hang :)

I can't find the help page for Abel second kind, class B. 

Maple has help page for Abel second kind, class A and Abel second kind, class C. But not for class B. 

Here is an example of Abel second kind class B

ode:=(3*t*y(t)+y(t)^2)+(t^2+t*y(t))*diff(y(t),t)=0;
DEtools:-odeadvisor(ode)

I wanted to know the difference and the transformation used for class B to make it Abel first kind.

I googled and can't find it. Also local help skips over class B.

Is this documented somewhere else?

btw, find error on the help page for class A. Transformation used is wrong. Will leave this for another question.

I have repeatedly seen this on two Windows PCs:

The assignement operator := is rendered as a roman d

This happens after using Maple for some time.
 Exiting Maple and restart of Maple is required. Has someone noticed the same?
All on Windows 10 and for sure in screen reader mode (my default, cannot report on the new GUI).

It seems that the new Ribbon interface has several bugs (probably an update will come soon). So, not only the Export As is not working, but I see that (at least in Windows), opening a worksheet with a large output will display the output using the Maple input font.
Just save a .mw with the content:

expand((x+1)^200);

and then open it.

hello everyone,

I am a bit shortsighted even with my glasses.

So my question is easy :: is there a way that when I open a (new) worksheet the magnification is 150%.

I can do it easily by hand but I am looking for 'something' in my maple.ini file to do this?

As well with the help pages.

Because even if I have a 150% magnification and I call a help page the display is still 100 % not 150%.

A part that I would like to set for every session a Digits:16 .

In the .ini file where I must input this? A ";" or not?

Thank you veru much.

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?

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?

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.

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

I found this version after Maple 2025 installation in Windows programs menu. It looks like a fully functional Maple version using the old GUI.

Why is it called "for screen readers"? I do not understand the link to persons with disabilites (I assume that the icon stands for it)?
In which respect is the new GUI less suited for visually impaired(?) people? I think the readabilty of the new GUI is at least as good as the old GUI.

In case Maple 2025 for Screen Readers is a fully functional Maple version, I give two thumbs up to Maplesoft. Smart move not to immediately impose a "disruptive" new GUI with allot of potential for new users to everyone.

On Ubuntu 24.04 or LinuxMint 22.1 (based on Ubuntu 24.04) I have the problem with(Matlab) funtions functionality

Matlab[openlink]();
Error, (in Matlab:-openlink) There was a problem initializing the Matlab engine. Refer to ?Matlab,setup for help configuring your system to work with the Matlab-link.  The error was: Maple/Matlab Link: Can't start Matlab engine; environment variable $MATLAB_BASEDIR not set

+ other error mesages from CLI:

starting mmatlink
In connectToMatlab
/bin/csh: /opt/MATLAB/R2024b/bin/glnxa64/libbsd.so.0: version `LIBBSD_0.7' not found (required by /bin/csh)

MATLAB R2024b using obsolete libbsd ver. 0.4.2 !!! So this is probably the problem...

$MATLAB_BASEDIR is properly defined at maple script:

# In order to link to MATLAB from within Maple, correct the following path
# and uncomment the next four lines, or define the environment variable,
# $MATLAB_BASEDIR outside this script.
if [ -z "$MATLAB_BASEDIR" ] ; then
MATLAB_BASEDIR=/opt/MATLAB/R2024b
export MATLAB_BASEDIR
fi

# C-shell is required for link to MATLAB (sudo apt install csh)

Any help???

Does Maple 2025 have a dark theme or GUI color customization?

Neither dragging the Maple Window to the screen edge nor Windows key & Arrow keys works on my
Windows 10 machine.

Is this only my installation?

Anything I can do get normal Windows windows behaviour back?

I've posted this issue in the beta forum for Maple previously, but apparently this issue was never addressed, so I am going to repost it here.

Contrary to Maple 2024, components like TextArea now ignore the general view zoom factor in Maple 2025.

I'll submit it as a software change request once Maple 2025 is on the list.
