It depends on how your code is.
You may see the below example, where I am saving the output into mat file in a loop .
clc; clear all ;
for i = 1:10
x=randn(1,1000);
out(i,:)=x.^2;
if i == 1
filename='myfile.mat';
save(filename,'out','-v7.3'); % save to MAT file
else
save(filename,'out','-append');
end
end
Note that out can be initialized knowing the loop. there are many other ways too to save the output.

No, you didn't understand me if i have this code for example:
clc;clear all;
for i=1:10; a=i+5; end
the final value of a =15 , i need a =[ 6 7 8 9 10 11 12 13 14 15];
thanks
