function [L,R]= LR(A)
R=A;
L=eye(size(A,1));
n=size(A,1);
for j=1:n-1
for i=(j+1):n
L(i,j)=R(i,j)/R(j,j);
R(i,:)=R(i,:)-L(i,j)*R(j,:);
end
end
end
Hi, i acually do not really understand, why I am only getting L, but not R,

The reason is likely the way you are calling your ‘LR’ funciton.
If you request both outputs, your function will deliver them:
A = ... ;
[L,R] = LR(A)
That call should return both outputs.

You didn’t state the matrix you are using as an argument, or what output you want from your funciton.
This works when I run it:
A = magic(4);
[L,R]= LR(A)
returning:
L =
1 0 0 0
0.3125 1 0 0
0.5625 0.56627 1 0
0.25 1.3012 -3 1
R =
16 2 3 13
0 10.375 9.0625 3.9375
0 -8.8818e-16 -0.81928 2.4578
0 -2.6645e-15 0 -2.6645e-15
Your function may only work for square matrices. If that is the case, you need to test for that, and return the appropriate outputs from your function, including an error condition and notification if the matrix argument is not square.
