HP Prime: Vector field CURL(). How-to...

In the manual p. 327 is an example of the CURL function in CAS mode.

This is the error I get when I try to reproduce:



Error: Bad Argument Type" Bad Argument Type"

What am I doing wrong?

Thanks in advance,



Is that a typo w/ respect to the open double quote without a corresponding ending one?

1. curl is presumably a symbolic calculation, so you should be in CAS mode

2. If you are using RPN mode, that would also affect the behavior.


This is the error I get when I try to reproduce:


One pair of brackets too much, it should be:


And it only works in CAS mode.




You were right with the double parentheses. That solved it.

I entered the function as curl([],[]) first and then filled out the two single line matrices individually.

Thanks for your help. I can now move on to the Laplace transform after half a day lost.




Thanks for your response. I finally figured it out. (See below.)
