Assigning values to a list.
in [Mathematica]

From: kevin on 1 Jun 2010 04:23 Hi Guys, I am a newbie to mathematica..Is there anyway to read values from 2 lists {n by 1} and {n by 1} to a new list {n by 2} without using loops.. eg say you have x = {1,3,5} any y = {2,4,6}, I will need a new list z ={{1,2},{3,4},{5,6}}.. Thanks in advance.

Thanks in advance. Transpose@{x,y} Or more customizable: MapThread[List,{x,y}] (where List could be a different function)

From: Michael Stern on 1 Jun 2010 07:41 You will get a lot of responses to this. If the lists are the same length, you can do it easily. z==Transpose[{x,y}] Michael On Jun 1, 2010, at 4:24 AM, kevin wrote: > Hi Guys, > > I am a newbie to mathematica..Is there anyway to read > values from 2 lists {n by 1} and {n by 1} to a new list {n by 2} > without using loops.. eg say you have x == {1,3,5} any y == {2,4,6}, I > will need a new list z =={{1,2},{3,4},{5,6}}..
