How to compute a square i.e. a*a?

I've a column matrix Y which is mx1.
I like to get the squares of all elements in m.
i.e. something like a*a (e.g. 2*2 = 4)
Due to the matrix nature, I cant just use Y*Y since you cant do a mx1*mx1.
So, how do I do a simple a*a so I could get all my elements in Y as m^2 x 1?
Thank you.
