Errors are printed for all values.
The '~=' in the code doesn't seem to be working for each element i.

You may consider difference of the columns you want to find whether the numbers are different or not.
d1 = Li_m_full10(:,1)-Ri_m_full10(:,1) ;
d2 = Li_m_full10(:,3)-Ri_m_full10(:,3) ;
In the above id d1 or d2 has zeros, then the numbers are equal, if not they are different.
