All of your questions are answered in detail in my Answer in this thread.

Both of your questions are answered in detail in my Answer.

Preben, your modifications work because they both return a two-member list even when they are passed symbolic arguments. See my much-more-detailed Answer.

@Sergio Parreiras I am eager to hear how any of your explorations with Maple IDE go.

Here's another basic debugging command to add to my list above:

infolevel[all]:= 2;

The infolevel and printlevel can be adjusted to various levels.

From running your code with infolevel set, I see that some large polynomials in β are being factored, perhaps one of your input polynomials. I'd be interested in running the code on the individual factors to see if one of them generates the bug.

Is G really an Array (with a capital A), or is it a list? What about K? And what are their sizes? Is it 14 and 4?

I'd need to see the rest of the code, where you define BC, XY, and SOL. How about uploading a worksheet?

I'll sign up for this beta testing if at least one person on this list with a reputation higher than mine also signs up. So, if you're signing up, please let me know. Send me email if you want to keep it private.

Or, if any such person has a specific reason why they are not signing up (like, more specific than I'm too busy), please let me know.

I don't understand this line in your code:

B := select(A->abs(A[4])B[5,1]^2+B[5,2]^3+B[5,3]^4; #check

Could you either explain it or correct it?

@amiller Make your very first line of code

restart;

Let me know how that goes! I was able to get the plots, no problem. If it doesn't work, please upload your worksheet directly onto the forum (see the fat green up arrow in the editor). Maybe there are some other inappropriate invisible multiplication signs.

@Alejandro Jakubi Thanks. "View page source" works also then. Any idea what causes the long lines? I notice that they are always in a different font---looks like Courier.

If I were to rate various aspects of Maple based on the experience level required to use them, on a scale from 0 to 10, I'd say that using evalhf correctly would be level 3, and using it effectively would be level 4.5. If you're doing symbolic integrations inside an add loop, the savings you get from using evalhf are going to be miniscule. Nonetheless, I will post an answer to your question.
