>> 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?

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