Vector manipulation by changing order or numbers in a vector.

I have the vector

a = [4 5 7 8 9 10]

I would like to make a new vector with the second element first and the first element last. How could I do this? Also I would like the same manipulation to occur regardless if the numbers or amount of numbers change.

Thanks,

So example for this vector when manipulated it would be

a = [5 7 8 9 10 4]

Edit

a = [4 5 7 8 9 10]
b=circshift(a,[0 -1])
