HP Prime: Vector field CURL(). Howto...  Chris Tvergard  09262013 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: "curl([[2*x*y,x*z,y*z],[x,y,z]]) Error:"curl([[2*x*y,x*z,y*z],[x,y,z]]) Error: Bad Argument Type" Bad Argument Type" What am I doing wrong? Thanks in advance,
Chris
Re: HP Prime: Vector field CURL(). Howto...  Han  09262013 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.
Re: HP Prime: Vector field CURL(). Howto...  fhub  09262013 Quote:One pair of brackets too much, it should be: curl([2*x*y,x*z,y*z],[x,y,z]) And it only works in CAS mode.

Re: HP Prime: Vector field CURL(). Howto...  Chris Tvergard  09262013 Franz, 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.
