灰色聚类MATLAB代码问题 灰云模型

做论文的时候需要用灰云模型，但现在不会编写灰云模型的多指标得分和权重的代码，大概了解云模型的代码含义，希望有灰色聚类MATLAB代码或灰云模型代码经验的专家指导，有偿。灰色聚类的代码只能做到以下程度：

clc;
N=1500;
Exsum = [25 60 75 85 95];
Ensum = [8.33,3.33,1.67,1.67,1.67];
Hesum = [0.83,0.33,0.17,0.17,0.17];
for a=1:5
    Ex1=Exsum(a);
    En1=Ensum(a);
    He1=Hesum(a);
    
   for q=1:N
    Enn1=randn(1)*He1+En1;
    x1(q)=randn.*Enn1+Ex1;
    if(x1(q)>=95)&&(x1(q)<=100) 
      y1(q)=1;
    elseif(x1(q)>=90)&&(x1(q)<95) 
      y1(q)=exp(-(x1(q)-Ex1).^2./(2.*Enn1.^2));
    elseif(x1(q)>=80)&&(x1(q)<90)
      y1(q)=exp(-(x1(q)-Ex1).^2./(2.*Enn1.^2));
    elseif(x1(q)>=70)&&(x1(q)<80)
      y1(q)=exp(-(x1(q)-Ex1).^2./(2.*Enn1.^2));
    elseif(x1(q)>=50)&&(x1(q)<70)
      y1(q)=exp(-(x1(q)-Ex1).^2./(2.*Enn1.^2));
    elseif(x1(q)>=25)&&(x1(q)<50)
      y1(q)=exp(-(x1(q)-Ex1).^2./(2.*Enn1.^2));
    else
      y1(q)=1;
    end
axis([0,100,0,1]);
   end

plot(x1,y1,'r*');
hold on;
end
