for variable = first : last
   got_error = true;
   try
     do something risky here
     got_error = false;     %only gets here if the risky thing worked
   catch ME
     do something about the error; the details of it are in ME
   end
   if got_error
     we had an error and did something with it but maybe we want to know that later
   end
 end

hi mr roberson

i fix this problem (do something risky here) by

if (strcmp(me.message,'my intended error.'))
  do something about the error;
 else
        rethrow(me);
end

thank you about your perfect comments.
