matrix plotting

If I have a matrix x=[1 2 3 4] and a vector y=[1 4 9 16] and make the matrix z=[x; y] what is the equivalent matrix plot of z to scatter(x,y).

[Sean de Wolski]

scatter(z(1,:),z(2,:))

or

scatter(z(1:2:end),z(2:2:end))

For that to work it would have to be scatter(z(1:(numel(z)/2)),z((numel(z)/2)+1:end)) but that's not what I'm trying to plot. I want to row 1 vs. row 2. Is there a way to call the row of a matrix?
