You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: eleme_molecule.m
    path of file: ./repos/RMD_Digging/chemi_mechanism
    
    the code of the file until where you have to start completion: %scrit file name eleme_molecule
%purpose:
%This program is used to add atom element to t
    
function elenummatch=eleme_molecule(elenummatch,elementname)
[row,~]=size(elenummatch);
for i=1:row
   if strcmp(elementname,elenummatch{i,1}) 
       elenummatch{i,2}=elenummatch{i,2}+1;
       break
   end
