how to delete outliers?

Hi I want to delete my outliers and ı used grubbs test. Now ı want to apply 2 sıgma rules which is a little bit different from Grubbs test. I wrote codes but ıt gives me error messagge.

 mu=mean(eingabe{n,m});
            s=std(eingabe{n,m});
 outliers= eingabe{n,m}< mu-2*s & eingabe{n,m}> mu+2*s  ;
 outliers2=  eingabe{n,m}< mu-2*s;
 eingabe{n,m}(outliers)=[];

I think & work does not there. Do ı have another options.Could you please help me?

Replace & with OR (|); eingabe cannot be smaller mu AND (&) larger mu at the same time:

 outliers = eingabe{n,m} < mu - 2*s | eingabe{n,m} > mu + 2*s;

That should work. If it doesn't please tell us a bit more about what eingabe{m,n} is and what went wrong.
