To add two lists.

[robierzo]

I need to add two lists. Add one to the list each member of the list2. The result would be the list3.

(setq lista2 '((0.0 14.127) (10.314 6.634) (6.374 -5.491) (-6.374 -5.491) (-10.314 6.634)))
(setq lista1 '(150.0 200.0))

The result:

lista3 ((150.0 214.127) (160.314 206.634).......(139.686 206.634))

(append (list lista1) lista2)

RenderMan, It's not right. You must use mapcar and lambda. But do not know how

[Tharwat]

(foreach x lista2 (setq l (cons (list (+ (car x) (car lista1)) (+ (cadr x) (cadr lista1))) l)))
(reverse l)

(mapcar '(lambda ( a ) (mapcar '+ a lista1)) lista2)

O.K. Thanks to all three. Lee Mac option is what I wanted.

Respectfully, you neglected to specify the requirement for Mapcar and Lambda in your original post.

I try not to suggest the more complex functions, when one neglects to demonstrate knowledge of the simpler (in this case Append)... Most certainly not because I think I know more than others, but simply that is how I learned.


Second, had you tested the code I posted, you'd see that it does what you demonstrated in your original post (appending lista1 to the front of lista2).
... I stand corrected.

Thankfully, other(s) have already answered your question, given the supplemental criteria.

Look a little closer at the OP's requirement Renderman - the solution that you proposed is not equivalent to the others posted in this thread.

Post corrected.

Sorry. My English is the English translator of Google. It is archaic and poor, but I do not know more. I express myself best I can.
Thank you.
