how do I create a table in a nested loop

there are nested for loops. I want to save them(sonuc) in the table.

I want to create a table with the 'sonuc' data, I want to see all the data in the same place, but it is repeated because it is in the loop.

Thank you very much in advance

clc
clear

mu0=10.5; sigma=1; alfa=0.05;den=1000;
n=10;nson=50;topz=0;topt=0

for mu0=10.5:0.5:11.5
    mu0;
    for n=10:10:nson
    n;
    for i=1:den
    x1=normrnd (mu0,sigma,1,n);
    x2=trnd(mu0,n-1);
    [rz, pz, zh]= ztesti (x1,mu0,sigma,alfa);
    [rt, pt, th]= ttesti (x2,mu0,alfa);
    
    
    end
topz=topz+rz;
topt=topt+rt;
roz=topz/den;
rot=topt/den;
sonuc = [mu0, n, roz, rot]
end
end

Hi @hanife gürdal,

I understand that you want to create a table to save "sonuc" variable value that is getting updated within a "for" loop.

You can achieve this using following steps:

1. Create a empty table and set its header name as "mu0","n","roz" and "rot".
2. Add the updated values of "sonuc" to the table inside the "for" loop.

The updated script, after adding above steps, is provided below:

clc
clear
mu0=10.5; 
sigma=1; 
alfa=0.05;
den=1000;
n=10;
nson=50;
topz=0;
topt=0;

header={'mu0','n','roz','rot'}; % header of the table
sonuc=cell2table(cell(0,4),'VariableNames',header); % empty table

for mu0=10.5:0.5:11.5
    mu0;
    for n=10:10:nson
    n;
    for i=1:den
    x1=normrnd (mu0,sigma,1,n);
    x2=trnd(mu0,n-1);
    [rz, pz, zh]= ztesti (x1,mu0,sigma,alfa);
    [rt, pt, th]= ttesti (x2,mu0,alfa);
    
   
    end
topz=topz+rz;
topt=topt+rt;
roz=topz/den;
rot=topt/den;
sonuc = [sonuc;table(mu0, n, roz, rot,'VariableNames',header)]; % adding data to the table.
end
end

Please refer to the following documentation for more information on "table":
