MATLAB: About “Matlab Fctn” block

simulation

I included a for loop in the ML Fctn block.
function [xtest] x=(k)
for i=1:10
x=i
if (i>5)
x=k
else
x=i
end
end
I connected the output (x) to a "Time Scope" block. After the model runs for 20 sec, the Time Scope plot only the final value of x (x=k) instead of different values of x (1,2,3,4,5,5,5,..). How can I store or plot out all values of x? disp(x) will display values of x in Matlab window but I want to either store or plot x out (not just the final value).
Thanks.
Thanks.
I connected the output (x)

That's because the output of your Matlab Function block is the result of your for loop. The output is not the result of each iteration. You can use persistent declaration without a for loop, because Simulink will run your function automatically each step.
function x=fcn(k)
persistent i
if isempty(i)
 i=0
end
i=i+1
x=i
if i>5
 x=k
else
 x=i
end
