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.

Hi all, I have recently started playing around with Maple after using Mathematica for years. I am trying to understand how to do pattern matching in Maple, and am being frustrated by the following example using indices:

patmatch(S[a],S[b::symbol])

I would expect this to evaluate to true when none of the symbols have been given other meanings, but this isn't the case. For the life of my I can't work out what I'm doing wrong, and have been unable to find an example of pattern matching with indices online. What am I missing here?

The equivalent statement using functions:

patmatch(S(a),S(b::symbol))

returns true as expected.

Many thanks in advance!

I’m absolutely delighted to announce the launch of Maple 2025!

Although you see a new release every year, new features take anything from a few fast-paced weeks to develop, to months of careful cultivation.

Working on so many features in parallel, each with varying time scales, isn't easy! We have to fastidiously manage and track our work.

So it's easy to lose ourselves in the daily minutiae of software development. To help us maintain perspective, we constantly ask ourselves questions like:

• What user problem are we solving and how often does this problem occur?
• Can we validate our proposed solution with preliminary user feedback?
• Is this a solution to a problem that doesn't exist and will never exist, or are we pre-empting a future need?
• Are we offering value to our users?

Given the answers, we course-correct to make sure we stay on track for our central mission - to make you happy, and to keep you coming back year-after-year.

With Maple 2025, I think we've smashed that goal. We have many new features that'll appeal to many different types of users - from students, educators and mathematicians, to engineers, scientists and technical professionals

Let me walk you through some of my personal highlights.

It’ll be difficult for anyone to miss this - Maple 2025 has a new interface! It’s a ribbon-based UI that look clean and contemporary, and helps you find and discover tools more quickly than before.

You have large, meaningful icons.

Items are logically grouped.

The ribbons is contextual. If you click on a plot, you get new tabs for interacting with and drawing on the plot.

A new Education tab collects pedagogical resources that were scattered around the interface in prior releases.

This is the biggest visual overhaul to Maple in many years. We hope you like it! 

We also appreciate that changes in look and feel can be divisive. Please rest assured that we will refine and finesse the interface with each successive release; your comments and suggestions are most welcome.

The new interface is available on Windows and Linux, and as a technology preview on Mac.

The right arrow key on my keyboard is wearing out…and it’s all because of Maple. I’m knee deep in Maple nearly every day entering equations, and I’m always using right-arrow to move the cursor. It gets kind of tedious!

This anecdote reflects some investigative work we did. We comprehensively examined our internal library of thousands of Maple worksheets and discovered that these three input patterns are extremely common.

Previously, you’d use the right-arrow key to move the cursor out of the exponential, division or subscript.

Now, in Maple 2025, when you

• type ^, /, or enter a literal subscript with a double-underscore,
• followed by a number or symbol
• and then input another operator (such as +)

the operator is automatically inserted on the baseline (except when y = 1).

Of course, you can also make the cursor return to or stay in the exponent or denominator with a simple keystroke, when that is what is needed.

This is one of those little quality of life refinements that I’m very fond of - it’s a little visual and usability dopamine hit.

The sum command (and its typeset form) now indexes into vectors without you needing to spam unevaluation quotes all over your expression.

We’ve been integrating units deeper into the Maple system, release after release. Much of this is driven by our engineering users.

A few releases ago, we made int(numeric) compatible with units. With Maple 2025, you can now numerically differentiate  expressions and procedures that have units.

I’m a grizzled thermodynamics hack, so here’s an example in which I calculate the specific heat capacity of water by differentiating enthalpy with respect to temperature (and then confirm the result with the built-in value):

This is in addition to many other improvements to the units experience.

Although this is a part of Maple that I don’t touch often (my colleague Karishma takes point on the education side), I REALLY wish I’d had this when I was struggling with math.

You can now automatically generate unlimited variants of the same problem for students to solve with the Try Another feature, which has been added to Maple’s Check My Work tools (another feature I really could have used!). This is available for many common math principles, including factorization, simplification, integration and more.

This is just one of the improvements in Maple 2025 for teaching and learning.

 If you’ve ever found yourself going back and forth (and back and forth) between two large, almost identical-looking Maple expressions, trying to figure out how they are different, you’re going to love this one.  ExpressionTools is a new package that lets you compare the differences between two expressions.

I really like the use of color to highlight differences. Less squinting at the screen!

You can now run Maple Flow worksheets from Maple (you don’t need Maple Flow installed to do this). You can send parameters into the Flow worksheet and extract your desired results.

This means you can use the entire flexibility of Maple to analysis and manipulate your Flow worksheet. You could, for example:

• Attach a Flow worksheet to a Maple workbook and create an interactive application
• Carry out parameter studies of a Flow worksheet by evaluating it over many parameter sets in Maple
• Create an Excel interface for a Flow worksheet using the Maple add-in for Excel

Simplify is one of those functions that literally tens of thousands of people use each day. Every time we make an incremental improvement, the cumulative benefits across our entire user base are significant.

We’ve refined simplify in a number of critical ways. For example, simplify now recognizes when exponentials can be profitably converted to hyperbolic trig functions:

The analysis of many scientific phenomena result in Laplace transforms that do not have a symbolic inverse which can be expressed in terms of elementary functions. This includes applications in heat transfer, fluid mechanics, fractional diffusion processes, control systems and electrical transmission.

For example, this monster Laplace transform results from an analysis of voltage on a transmission line:

You can now numerically invert this transform courtesy of an enhancement to inttrans:-invlaplace - a fast quadrature method.

I’ve saved what I think has the most future potential for last.

I’m sure nearly all of you have experimented with the various AI tools. They’re an inevitable part of our present and future, whether we're comfortable with it or not.

This is something we've been mulling over for some time.

• In Maple 2019, the DeepLearning package made its debut. This package provides tools for machine learning, supporting operations such as classification and regression using neural networks.
• In Maple 2024, we introduced an AI-powered formula lookup feature.

In Maple 2025, we’re giving you an early-stage technology preview of AI-powered document generation.

You can automatically generate worksheet content by prompting an AI, and then gradually refine the content

If you’re an educator, you might want some content that describes applications of calculus. So you might ask the AI “How do I derive the formula for the area of a circle” by entering your prompt into this text box:

This is the worksheet content that may be returned:

If you’re structural engineer who wants to know how to calculate the hardness of concrete, you might ask the AI: “How do I calculate the compressive strength of slow hardening concrete as a function of time? Use the CEB-FIP Model Code 90. Include a worked example with Maple code”.

This worksheet content that could be generated (note the live Maple code):

We’re labelling AI-generated worksheet content as a technology preview. You might see

• text that might be misleading (but sounds plausible)
• code that doesn’t work (but looks plausible)
• or different results each time you click “Generate Document”

For the moment, I would not rely on AI-generated worksheet content without realistic expectations, a healthy dose of scepticism and a modicum of detached analysis. But AI models are rapidly growing in robustness, and we want to position ourselves to best exploit their future potential. The next few years will be VERY exciting.

We can never cover everything in a short blog post like this. So if you want to know more, head on over to the What’s New pages for Maple 2025!

I have a student who has a problem when closing and opening a Maple file.

It seems as if Maple turns math fields into text, but still execute when using ! or !!!

The dark red part is written in a text field, but Maple still executes

If I try to write in a math field and executes, closes Maple and opens again, this does not happen, so it is not the file that is the problem.  The student is running 2024.2 version.

Can anyone explain the problem and how to solve it.

I am unable to add a comment or the file. I have tried several times, without any luck

Update 

Also, is there a way to disable the use of remember tables permanently in Maple? This causes me so much trouble and It is cause of why Maple behave differently at different times.

Help shows how to do it if one knows the name of the module or procedure. But Maple has 1000's of these. There does not seem to be a way to tell maple

          forget(all)

and have set once. (may be something I can put in the ini file, to disable this feature).

At the end of help it says

"As a special case, specifying f as an empty range allows for selective clearing of remember table entries from all remember tables in the system.  This requires a second argument, to indicate which entries to clear. For example, forget(..,x), which will clear all remembered entries in the system that reference x.  "

But what is x in the above?? If I do forget(..) it does not work.

---- end update ------------------------------------------------------------------------------------------------------------------

Adding printlevel:=20, I see simplify generate/runs through longer code the first time. The second time calling the same exact simplify code, now it shows it runs through much shorter code. 

I am assuming printlevel is behaving correctly each time.

This must be due to cache simplifies keeps somewhere, or some internal settings it updates from first time and this is what causes it to do shorter run second time.

Without doing restart, how can make force simplify to run through same code it did the first time and each time? i.e. as if it was called the very first time each time?

I tried forget, but it is not doing anything.

Here is worksheet.  The code is simply this

printlevel:=0;
restart;
printlevel:=20;
simplify(3*x^3/x+sin(x^2)/4);  #long printout

simplify(3*x^3/x+sin(x^2)/4);  #short printout

printlevel:=0;
forget(simplify,forgetpermanent = true,reinitialize=true);

printlevel:=20;
simplify(3*x^3/x+sin(x^2)/4); #still same short printout

So there is something else needs to be cleared? Only way to get the long printout is to do restart. but ofcourse I can't do restart in middle of a loop.

I tried gc() also, but had no effect. 

What other commands are there to do this? I do use Physics and it is on my libname.

Anyone has Maple 2025 could check if same behaviour there also?

How to I generate and or export a plot without a white border or equivalently , just  the information inside the axes?

See example. Note that when I insert the content below, it fails to accurately copy the information( blue background). If you look at the attached maple file, it should be very clear what I'm after.

Hi,

I'm working on formatting my tables for export to PDF. Is there a way to align the text in the cells (to the left, for example)?

Thanks

I do not understand why select(has,-a^2,x); returns 1 but select(has,a^2,x); returned undefined.

Should not both return undefined, since there is no x anywhere in the expression?

I looked at help and do not see a clue so far.

Here is another variation, where I changed a^2 to a

Download select_question_v2_march_23_2025.mw

The good thing is that has(C,x) returns false in both case. So the problem is not with the has call. It is select which decided to return 1 when there is negative sign. But why?

a lot of time i have this issue when i want delete something it take a lot time to show the in this worksheet it happen too what is issue it is becuase all the text are not in text modde or what? and when i want copy and past my function to place with text is write null for me, what is problem?
and why in end of my display there is two graph?

Trying to use plot to connect a series of points for illustrative purposes, but the functionality seems to have broken in 2024 or else I'm overlooking something. Related/unrelated: When I copy the related code from the cell and paste it into another application (like a browser) the list of points is reversed: e.g. `

plot({[-1, -2], [-1, 1], [-1, 6], [3, -2], [3, 6]}, x = -3 .. 4, y = -4 .. 10, style = line)` 

(That was literally me copy and pasting the relevant code from Maple into this form.)

The plot in question can be seen below. Also to note, if I leave off the last [3,-2] point, it will correctly plot the graph. It's ony when I add in that last point that I suddenly get the shape I do below. 

In 1-D Math, subscripts can be found with crtl-F

In 2-D Math this does not work. 

Also powers of (^) cannot be searched in 2D-Math.

Are there any ways to perfom searches on subscripts or superscripts in 2-D Math?

Hi MaplePrimes,
I made a quick code to calculate Aliquot Sequences.

The code works.

I was inspired by a Numberphile YouTube video.

This should be helpful.
