Problem 56180. Boustrophedon

Given a vector v and a positive integer n, return an m-by-n matrix containing the elements of v row-wise, alternating left-to-right and right-to-left ordering:
You can assume that the number of elements of v will be an integer multiple of n.
For example:
v = 1:12;
boustrophedon(v,4)
ans =
1 2 3 4
8 7 6 5
9 10 11 12
boustrophedon(v,6)
ans =
1 2 3 4 5 6
12 11 10 9 8 7
v = [20 1 18 4 13 6 10 15 2 17 3 19 7 16 8 11 14 9 12 5];
ans =
20 1 18 4 13
17 2 15 10 6
3 19 7 16 8
5 12 9 14 11
