I just installed Maple 2023 on a MacPro running macOS Sequoia 15.7.2. Update to latest .version and activation worked without a hitch.

When I try to run it from the Finder it immediately puts up a dialog saying something like "Java not found". There is a webpage by Maplesoft addressing this, but it is completely uninformative and unhelpful.

I can get Maple to run using the cli (in Terminal) opening the Maple 2023 .app file, at which point Maple (running the standard GUI) works just as one would expect. So it is not a crisis but I'd like to be able to open it through the Finder as well. The Maple .app folder appears to have all the Java stuff in it, and clearly it is somewhere.

Anyone seen and solved this before?

Thanks,

Mac Dude

To enter prime notation in Math-2D I currently do

k^2 + `k'`^2 = 1;
                           2     2    
                          k  + k'  = 1

To enter a back tick (left single quote symbol) this requires with my keyboard shift+(key for `) followed by hitting the space bar.

The output looks nice

However to enter k' in a new input line, dragging and dropping k' (which normally works for other expressions) from a former output does not work. The result is

Instead of changing default typesetting rules, I made k' atomic and dragged it to the favourite palette. This is an acceptable solution to avoid keyboard acrobatics. The only drawback is that the favourite palette gets crowded after a while.

I was wondering whether there are other ways to enter prime notation in a less complicated way as I have described above?

This is a question on semantics I suppose.

Maple dsolve returns a solution with a limit in it, because the limit do not exist or Maple could not find the limit. Which is fine.

Then why does simplify() applied to the solution returns undefined?  Now it appears that Maple solution is y(x)=undefined, which does not make much sense.

Should it not have left the solution with the limit in place as is? i.e. since dsolve could not find limit, how did simplify managed to replace the limit by undefined?

Is this considered an expected behavior by simplify?

Firewall changed its mind again today and will not let me upload worksheet. Here is code

ode:=4*x*diff(y(x),x$2)+2*diff(y(x),x)+y(x)=(6+x)/x^2;
IC:=y(infinity)=0;
sol:=dsolve([ode,IC],y(x)); #OK, maple can't find limit. No problem
simplify(sol)

I have to ask my school teacher on this when school starts. But is it OK to have infinity in the ode solution itself?

Maple 2025.2 gives

ode:=diff(y(x),x$2)-2*diff(y(x),x)+y(x)=4*exp(-x);
IC:=y(infinity)=0;
sol:=dsolve([ode,IC])

And according to odetest, this does not verify the ode nor the IC

odetest(sol,[ode,IC])

Just asking what others think of this solution and if it should be consider a bug or not?

Maple 2025.2 on windows 10

in here i want to apply this method for finding my parameter but is a special kind of substituion and i don't know how hundle this kind  and find the parameters i did some part but i didn't reach the target

Solving this ode, Maple says 

But notice, the xi and eta tangent vectors order is reversed. Maple says pattern is [0,F*G], but shows [F*G,0].

Also, when later using DEtools:-symgen with HINT option, it does not return the above result. Tried both patterns with 0 on left and 0 on right. In both cases symgen does not return what shows above. 

Why is that? Am I doing something wrong? Notice also it says   "way=HINT"  but I am not using way option. Only HINT option, Why is it saying way=HINT? it seems argument passing I  am using is wrong, but do not see why it could be wrong.  This is what help says

Has anybody seen the unit palette beeing empty? 

This is new to me. I normally use the unit entry in the favourites but this time wanted to try Maple presets.

I have written about unit problems before. I thought an update would solve the problems, but no.

I have a very simple example here where the unit can't be changed:

In the first example I am using capital M for mass; now I can change unit on density.

I'm doing some experimenting with the Optimization:-Maximize and Minimize functions, and I'm having difficulties getting them to find the actual extrema within a set of bounds.  I have found that the extrema they identify depend on the bounds, even when the same extrema lie within those bounds. I've also tried the initialpoint option to start the solution near the extrema and I've found three things: sometimes it works to get the correct solution, sometimes it doesn't and sometimes I get a message saying the initial point was ignored by the solver.

The problems I'm using are all taken from the Maple help or tutorials.

I haven't included a bunch of test cases but I've attached the Maple Flow file.  I have a suspicion it has to do with the second derivatives of the functions near the boundaries, but I'm not sure.

Can anyone point me to more information, or am I doing something wrong?

Thanks for your help.

I know this is a "silly" question but just recently my Tool Ribbon disapears or "retracts" into thin air and I have to first click on it to get it to "deploy" downward and then when I click on it to "Insert, View, Edit..." it then retracts and is gone once I do the click.  I am forced to do 2 clicks when before I had only to do one click.  This is not efficient.  I like the Ribbon concept for Maple 2025 but this is an irritating annoyance.  If some one knowlegeable could please take a few seconds to reply to this, I would greatly appreciate it.  BTW, this just started.  In an other machine I have where Maple 2025 is located, it doesn't do this.   I am sure it is a simple setting somewhere.  I just can't find that setting.  Thank you in advance 

Hello,

The title is misleading.

I can't remember how to enter a vector ( I mean the symbol 'arrow' ) for a vector , say u.

I have a normal French/France kb , so please no Klingon reply :)

So CTRL+SHIFT+ALT+F6 is no answer.

Thank you,

Jean-Michel

I am not desperatly seeking Susan but the code of the DoFit procedure (for what this early-year joke is worth)

showstat(Statistics:-LinearFit)  reveals LinearFit uses the procedure Statistics:-Regression:-LinearFit (lines 4 & 9).

Next
kernelopts(opaquemodules=false):
showstat(Statistics:-Regression:-LinearFit):
indicates the Maple procedure which really does the LinearFit has name DoFit (lines 6 & 16).

I spent some time using the Library assistant to try and find this procedure, in vain.
Where can I get the source of DoFit?

Thanks in advance.

almost i did all the case but some case i determined in red color are not satisfy what is problem of them and how i can apply the case 47-52, beside this i changed the ode in eq(15) i didn't write rho parameter  is make any problem?

Hello everyone,

I'm currently evaluating MapleFlow and the transition from MathCad sheets to this software.

I was looking at temperature conversions and this seems to be wrong:

I was expecting 0°C after the conversion. Has someone an explanation for this?

Thanks for your help.

Hello Ladies and Genlemen,

What is the command to display a list of *all* the packages in Maple ?

How do you insert an output for exemple (2.1.1) in a worksheet?

CTRL+K is inactive for me...it just adds a CRLF.

Thank you very much and kind regards,

Jean-Michel
