Hi, I am confused with the definition of the three errors. Are they defined as follows?
L1 = sum(abs(uex-u))*dx;
L2 = sqrt(dx*sum((uex-u)^2));
L_infinity = max(abs(uex-u));
Is L_infinity always larger than the other two errors?

Then, you can define the norm in average or not, you can find some useful note in the book of LeVeque or any other book on numerical analysis.
L_infinity becomes the more restrictive
