Thanks again for the tip.

Thank you for your attention Mariusz. I have difficulty calculating the gradient with this numerical procedure.

 

eval(-Gradient(uval(r, t), 'cylindrical'[r, theta, z]), [r = 2, t = 4])

Thanks for the reply and attention.

Thanks for the tips, because I'm not familiar with some Maple functions yet.

I am grateful for the information.

Thanks for the tip.

I installed the new version of the Physics package and problem was solved.
Thanks again for your attention.

Thanks again for the good attention.

I  am attaching a Maple document for better understanding.Test_with_uses.mw

Yes it is true, but in the above procedure (gds) with the Physics package, the package commands are not confined to proc, they leak acting on external expressions. Check.
 

I questioned Maple's trivial answer because I saw in some textbook something using eigenvalues and eigenfunctions.
I am grateful for the information.

Yes, but I found the problem:
The problem occurred because I loaded package Physics and with it came the option assumingusesAssume = true (for the assuming command), which caused a conflict with the piecewise function.
Unfortunately we have to be careful to avoid these conflicts.

Thank you for your attention and response.

I  am grateful for the information. By the way, can you tell me where the Maple boot file is? I would like to insert some macros in this file.

Thank you,

Oliveira
