I am bit new in JQuery ,,I have a 2D Array 

2DArray =[2.0,6.31]
         [3.0,6.09]
         [4.0,7.44]

I want to split it into 2 One dimensional Array like this:

[2.0, 3.0, 4.0]    
[6.31, 6.09, 7.44]

I have read posts about convert single array into multidimensional array but not vice versa ...

Any suggestion would be helpful

    How do you expect to get at all the elements of the original array if you don't loop through them? – blgt Jul 07 '14 at 16:07

This should about do it, you have to loop:

var twoDArray =[[2.0,6.31],
         [3.0,6.09],
         [4.0,7.44]];

var xArray = [];
var yArray = [];

$.each(twoDArray, function(index, value) {
    xArray.push(value[0]);
    yArray.push(value[1]);
});

BTW 2DArray is an invalid variable name. You can't use 2 at the start of a variable.

Also your array declaration is invalid.

You could use the JavsScript map() method:

var twoDArray =[[2.0,6.31],
               [3.0,6.09],
               [4.0,7.44]];

var xArray = twoDArray.map(function(tuple) {
    return tuple[0];
});
var yArray = twoDArray.map(function(tuple) {
    return tuple[1];
});

Create 2 arrays for each row put first column in first array and second on in the second array. This link would give you all the array operation you have in jQuery.

http://learn.jquery.com/javascript-101/arrays/

Alternately you can even use a for loop with index.

Hope this helps. Happy coding.
