Storing value outside the loop using reshape function

Hello everyone!

I was working on some code and I can't silly I'm doing. Here I have attached my problem in short format. I know its still quite lengthy but please help me out. After hours I'm unable to figure out what I'm doing wrong.

l=[4; 2.8];
[mL,nL]=size(l);
A=[15.0 22.5 30.0 37.5 45.0 52.5 60.0 ]';

for h=1:2
  L=l(h);
  X=[L*100/16 L*100/10];
  XD = A(A>=X(1,1) & A<= X(1,2));
  [mX,nX]=size(XD);
    index = 0;
  for i=1:mX
    index=index+1;
    LL(index)=l(h);
    XDD(index)=XD(i);
  end
  A1 = [reshape(LL,[],1)];
  A2 = [reshape(XDD,[],1)];
  L=[A1 A2]
end

Running the above code gives following output:

L =         4           30
            4         37.5
            
L =         2.8       22.5
            4         37.5
            

Desired Output

L =         4           30
            4         37.5
            
L =         2.8       22.5

t seems the variables LL and XDD are uninitialized and so keep their value on the second iteration of the loop. What happens when adding LL=[]; XDD=[]; just under "for h=1:2" ?

Thanks @Stéphane Vaillant it work!

But if I have a huge script I have to initialize variables every time and for large number of variables it becomes hard. Is there any alternative for this?
