You can obtain a handle to the linked MATLAB function block using the following commands:  

 

   root = sfroot;
   model = getfullname(bdroot(BlockName));
   SFMachine = root.find('-isa','Stateflow.Machine','-and','Name',model);
   emlObj = SFMachine.find('-isa','Stateflow.LinkChart','-and','Path',BlockName);

where the variable 'BlockName' holds the name of the MATLAB function block you wish to modify. 

Once you obtain the emlObj, you can make the desired changes to the MATLAB function block from the command line.
