@rcorless 

Thank you for considering this summary worth publishing. This is unexpected. I was not sure about clarity and exactness – and I had no one to proofread it. I'm considering removing the student package calls, as I was informed that the package isn't designed for such cases. Perhaps I'll receive further feedback.

I entered the VA with

@rlopez

This much better than digging through Mapleprimes post.

 Thank you for clarifying.

@kjell 

I am surprised that there nothing usefull in Mapleprimes.

Can you be more specific about the problem you want to solve? The PDE and BC would make an answer easier. Uploading a Maplefile is helpful as well.

Does this help?

There is probably more to find in Mapleprimes

On my Windows 10 machine I observe per each nuge of the mouse weel a line feed as indicated here by the red ticks

(The system setting for themouse  weel is set to 3 lines).

What is the operating system of your machine?

Do you mean scrolling this page: help(pdsolve, numeric) ?

Other help topics or web pages like https://www.maplesoft.com/support/help/Maple/view.aspx?path=pdsolve%2fnumeric

scroll well?

How do you scroll? Mouse weel?

but again with 2023.1 (to be more precise).

I assumed that the simple package was also effective when dealing with units and 0. What are the remaing painpoints (apart from this bug)?

@acer 

I was in a remote place without internet and can only reply now.

With what I have learned in the meantime, I would ask differently in a less complex case. In this case, no further progress is needed.

Thank you for follwoing up on this!

@delvin 

The error message is quite clear. i is not defined. If you want to express the imaginary unit you should do it as matlab requires to enter complex numbers. Plot won't work with complex numbers. You have to decide for the real or imaginary part of Z.

sigma_p evaluates once to a value (yellow) but not the second time. The backticks red look strange. I think sigma__p and sigma__uts_p seem to be new names which are not assigned to values. Something went wrong when the names where entered.

@epostma 

Sorry, I did not intend to take so much space with that factoring example. At least it's a good benchmark for AI.

@sursumCorda 

Thank you! I will study this and try to make a link to help(examples, functionaloperators) where I could have deduced an answer  myself (see "Operators are distributive.").

@sursumCorda 

Explain(further): What does the "*" between content and primpart do in a fucntional operator and where the h... did you find this?

(Your magic statement will probably not work if the 2 was a positive real constant.)

Anyway, since you are human (I hope), I give you a mental thumbs up.

Since I did not understand in the above the need to enclose Explain in a display(…) command I searched in Maple with Alt+s for “display”.

The topics in help were not conlcusive.

What I tried next

display(Explain(display))

and got this answer back:

Display refers to visually presenting information or data, often on a screen or other visual output device. This can apply to many different scenarios, from a computer screen displaying a web page, to an LED sign displaying the time. "Display" can also refer to the way in which something is shown or presented, especially in exhibitions, museums, or trade shows. For instance, a store might create a holiday-themed "display" in their window, showcasing their top-selling products. In the technology world, "display" can refer to the hardware used to show visual output, such as computer monitors, televisions, or mobile phone screens.

I then searched the document for "display" and got the answer...

Overall, natural language models will be part of our future, if we like it or not. From this perspective it’s good that Maplesoft takes initiative. Hopefully Maplesoft will provide in the future an own model and we do not have to depend on third party models. Supervised learning by Maple users will likely improve the correctness of answers and exploit better the already existing knowledge base.

After having learned Maple the hard way by reading the documentation and consulting Mapleprimes and support, I do not see a need for me to chat. This might change the day when “MapleChat” can provide, for example, more examples and/or explanations on command options. Or the day when I can ask Maplechat to provide a command that factors sqrt(2) out of sqrt(2*a+2*b) . What we don’t need is something like that
