Dr. Scot Gould is a professor of physics in the W.M. Keck Science Department of Claremont McKenna, Pitzer, and Scripps Colleges - members of The Claremont Colleges in California. He was involved in the early development of the atomic force microscope. His research has included numerous studies and experiments using scanning probe microscopes, particularly those involving natural fibers such as spider silk. More recently, he was involved in developing and sustaining AISS. This full-year multi-unit, non-traditional, interdisciplinary undergraduate science education course integrated topics from biology, chemistry, physics, mathematics, and computer science. His current interest is integrating computational topics into the physics curriculum. He teaches the use of Maple's computer algebraic and numerical systems to assist students in modeling and visualizing physical and biological systems. His Dirac-notation-based quantum mechanics course is taught solely through Maple.

@charlie_fcl I understand ... and can reproduce this odd error. I guess the simple answer for now is, "If it hurts when you move your arm that way, then don't move your arm that way."

I suspect your post here will generate a bug report. (I wasn't able to generate one on the beta site.) 

Can you provide a link, or more details as to where you saw this file mapleflowrc, please? 

As for my copy of MapleFlow 2021.2, there are only 4 palettes: Expression, Units, Greek and Matrix. Personally, I would like to see more palletes. Help shows no way to include more palettes as one can do in Maple. 

I too copy into Word documents on ocassion. 

I notice that when posting from 2021.2 to Word 365 (Windows), the 2D plot "pastes" correctly, but the 3D plot does not, regardless how the copy command is performed. Fortunately, "Snip and Sketch" does work properly for both plots. 

I suspect someone at Maplesoft will test such transactions and get back to us. 

Maplesoft is aware of this problem.

The best I've seen for programmatically setting the fps value was answered here: which I agree is less than intuitive. 

Otherwise, given the default of 10 frames-per-second, yes, for a long process then lots of frames are generated. (frames = time * fps) However, at worst, the maximum error for the entire period of the animation should be within 1/20th of a second.  Increasing the fps would decrease the error.

I would like to see Maplesoft add 'fps' = as an option in plots:-animiate, if possible. Based on a search here in Maple Primes, this request is at least 10 years old. 

While I understand it is useful to revisit how content is presented, sadly, I'm no fan of the interface.  Several of my comments mimic others.

1) I too, don't care for the "blue" image the appears when one places the cursor over an app. I wish to click on the author. 

2) I too want to search by author. 

3) I do like the "More like this" offering.

4) I agree that the homepage should have tag-labeled tiles, not some applications. It took a while to scroll through all the tags before I found the one I wanted.

I assume you haven't labelled all applications yet. And the "Physics Student" collection appears to be empty. 

From the older application center, I prefer to the left menu bar which lists "catagories". My biggest complaint - it is sooooo slow that frequently it doesn't load or I get the "We are currently experiencing technical difficulties."   Sigh. 

I return to it enough that it motivates me to ask, is there any chance you might write a few more "programming in Maple" summaries? 

Until your preference is satisfied, may I suggest using, what I believe is, the same help content found on the web? With browsers, one can set up multiple pages from help to appear in tabs with a single click.

I often do have multiple help pages open simultaneously.   and usually a chapter or two from the programming guide:

@Pepini setting the grid to [200,200,200].  Is this smooth enough?

I would also like to see some type of consistency in the eigenvalue / eigenvector output. Your question is one that has been asked in various forms in MaplePrimes starting from this one from 2010:

As it has been pointed out, the sorting method used by Maple for sets is very helpful in both usage and readability. 


Your question, after my poorly worded response, deserves a more detailed answer. Hence, I’ll attempt to explain why 2d-input in Maple is crucial.

2d input, with the ability to use palettes, allows both the new user and the non-user to better read and understand the mathematics that is being performed. By highly reducing the amount of monospaced coding syntax, 2d-input is a catalyst for new users to solve mathematical problems that, historically, have been ignored. This is because such problems have been viewed as either too computational or mathematically difficult or required too much start-up cost to learn the coding necessary to solve.  This reality is reproduced every year in my computational math course for physics and engineering majors where students use both Maple and MATLAB to solve math problems typically found in undergraduate physics or engineering courses.  With 2d-input in Maple, where the “code” looks like mathematical symbols, students spend more time working on translating the mathematical symbols and operations into their personal language/narrative and less time translating that which they do not fully understand, the mathematics, into yet another set of symbols and operations, i.e., the programming code. (I should explain that once we have covered the mathematics using Maple to do the grunt work, I switch to the MATLAB code. MATLAB still is too popular in research environments.)

And like any spoken & written language, if one is not using the language constantly, one forgets it. It my experience that students can leave the coding environment for a semester and relearn 2d-input Maple more quickly than they can relearn the limited MATLAB they know. And this is true even for students who spent an entire semester learning how to code in MATLAB.

Finally, it is my experience 2d-input is so highly readable that people who are not familiar with Maple can quickly comprehend the operations and functions.  Hence my colleagues, who were all raised with Mathematica, MATLAB and/or Python and were initially opposed to the use of Maple in our department, have become accepting of students using Maple. Since they can read Maple 2d-input, it makes their lives easier. They do not have to learn another coding language.

Personally, there are times where I prefer to write a procedure in 1d-input. There are some very cool 1d-input coding features in Maple.  So, I recognize there is value in the Maple programming language and syntax. But for most projects which I must share with newer Maple-users or non-users, 2d-input, with its highly readable format, is the most effective tool I have for solving computational mathematical problems.

I hope this clarifies my unintentionally snarky “I’m not going there” comment.



I misspoke. I should have said, “Given my situation, I am not going to be able to ‘go there’.” I.e., to 1-D input, even though I do write Maple code this way.

However, you ask an excellent question that Maplesoft must be able to answer. And you do it with an important prompt, “Is 2D-input anything more than a pretty display?”

In my view, 2D-input is a major reason why I don’t just follow the rest my colleague and switch 100% to MATLAB and Mathematica – the leaders of mathematical software products in physics and engineering.  Tonight, I don’t have time for a follow up, but I wanted to make sure you are aware I appreciate your reply.

@tomleslie Thanks. I tried this ideas, but didn't think about 1-D. Since I'm not going there, this is not an option.  I like a number of the new features and plan to stick with it regardless of some of the new annoyances. 


Thanks for adding the ability to call dsove, numerically, with vectorized functions. Between that, and the improvements in the document mode, I see a significant paradigm shift in how I as a college instructor can use Maple as both document of readable "code" and a way for students to code with a minimal amount of teaching code.  

I quickly coded up a example of being able to write vectors differential equations using "dot notation", solve them numerically, and Explore the output using the parameterized option in dsolve, numeric.  Much of it takes advantage of the fact that: 

           Maple math = real math.

Here is a quick screen shot of some of this "coding while writing" 

This additions continue to move improve an impressive product.

@Christopher Tocci 

Yep, I missed it. I suspected it was "too good to be true."

Given that it looks like there is only a numerical solution, here is an alternative numerical approach that you might find useful - Explore. I guessed on some ranges. (S = separation, d = diameter..)
