Matlab question about code

>> D_pre

D_pre =

    0.2000    0.7000    0.4500    0.1000
    0.3000    0.4000    0.3700    0.6000

[righe_d, colonne_d]= size(D_pre)
coordinate=zeros(2, colonne_d)
for i=1:colonne_d
    coordinate=D_pre(:,i)
end

I want to have in output all the components of coordinate variables. I have to obtain:

0.2
0.3

and

0.7
0.4

and so on. In coordinate variable I have only the last that I want to obtain. How Can I modify the code?

[righe_d, colonne_d]= size(D_pre)
coordinate=zeros(2, colonne_d)
for i=1:colonne_d
    coordinate(:,i)=D_pre(:,i)
end

However if D_pre has the coordinate, you can simply use it as it is in your code? Why copying a variable?
