how to store data for second looping

Hi everybody, dataA consist of 20 'y' values.

Then, if 'diff' is more than 0.01, the code will looping back. How i can store value of dataA for each 'z loop'? Thank you.

for z=1:1000;
    
        for i=1:20
            x(i)=rand
            y(i)=2x(i)+1
         dataA(i,:)=y
        
        end
        
         diff=max(y)-min(y)
         
         if diff<0.01
             return
         
         else
           z=z+1
         end
end

One way would be to use a 3D array for dataA variable or;

for z=1:1000
    for i=1:20
        x(i)=rand;
        y(i)=2*x(i)+1;
    end
    dataA(z,:)=y;
    diff=max(y)-min(y);
    if diff<0.01
        break;
    end
end

You do not need to assign dataA to y(i) inside the loop.

You do not need to define z = z+1, "for loop" does it automatically.

Instead of return, I suggest you use break as well.

hi, The coding works fine and the data can be save now. Thank you.
