Desplazate a vector one unity to the right.

I have a vector of lenght N, I want to have another vector with the same size but translated to the right. Ex:
x=n1:n2;
y=x(n)-x(n-1);
It's like an discrete differenciation.
Any idea of how to do that?

You can define
y = x(2:end) - x(1:end-1)
or you can use the built-in routine
y = diff(x)
However, either way this only defines N-1 values and does not define what the N'th value should be.
