    mean1=[10;70;90;20];
  class1='ST';
  class2='AK';
  class3='SN';
  for j=1:size(mean1,1)
      if (0<mean1(j))&(mean1(j)>=60)
      class=class1
      end
      if(61<=mean1(j))&(mean1(j)>=80)
      class=class2
      end
      if(81<=mean1(j))&(mean1(j)>=100)
      class=class3

mean1=[10;70;90;20];

class1='ST';

class2='AK';

class3='SN';

out = [];

for j=1:size(mean1,1)

if (0<mean1(j))&(mean1(j)<60), class=class1;

elseif(61<=mean1(j))&(mean1(j)<80), class=class2;

else class=class3;

end

out = [out;{class}]

end
