score=[100 88 70];
aver=mymean(score)
underaver=myfind(score,aver)
function value=mymean(score) %求平均值
len=size(score,2);
sum=0;
for i=1:len
sum=sum+score(i) ;
end
value=sum/len;
function value=myfind(score,vargin)%求低于平均分的值
len=size(score,2);
A=null(1);
for k=1:len
if(score(k)

再答： database=struct('name',{'����','����','����'},'score',{100,88,70}); disp('ѧ��ƽ��ɼ�Ϊ') aver=mymean([database.score]) underaver=myfind([database.score],aver); disp('������ѧ��Ϊ') disp(database(underaver)) function value=mymean(score) %��ƽ��ֵ len=size(score,2); sum=0; for i=1:len sum=sum+score(i) ; end value=sum/len; function value=myfind(score,vargin)%�����ƽ��ֵ�ֵ len=size(score,2); A=null(1); for k=1:len if(score(k)
