MATLAB报错未定义函数或变量怎么破啊？附代码

Question

%%-----------------------------------------------------------------------------------------------------------------
% fobj 评价函数

% dim 变量的个数

% Max_iteration 最大迭代次数

% SearchAgents_no 种群规模

% lb=[lb1,lb2,...,lbn] lbn 是变量 n 的下界

% ub=[ub1,ub2,...,ubn] ubn 是变量 n 的上界

%%-----------------------------------------------------------------------------------------------------------------

% 位置更新函数

[Alpha_score,Alpha_pos,Convergence_curve]=GWO(SearchAgents_no,Max_iter,lb,ub,dim,fobj)

% 初始化alpha, beta,和delta_pos
Alpha_pos=zeros(1,dim);
Alpha_score=inf;

Beta_pos=zeros(1,dim);
Beta_score=inf;

Delta_pos=zeros(1,dim);
Delta_score=inf;

%初始化灰狼个体的位置

Positions=initialization(SearchAgents_no,dim,ub,lb);

Convergence_curve=zeros(1,Max_iter);

l=0; % 循环计数

% 主循环

while l<Max_iter
for i=1:size(Positions,1)

    %  边界控制

     Flag4ub=Positions(i,:)>ub; 
     Flag4lb=Positions(i,:)<lb; 
     Positions(i,:)=(Positions(i,:).*(~(Flag4ub+Flag4lb)))+ub.*Flag4ub+lb.*Flag4lb;                

     %  计算评价函数

     fitness=fobj(Positions(i,:)); 
      %  更新 Alpha, Beta  和 Delta 
     if fitness<Alpha_score  
         Alpha_score=fitness; %  更新  alpha 
         Alpha_pos=Positions(i,:); 
     end 

     if fitness>Alpha_score && fitness<Beta_score  
         Beta_score=fitness; %  更新 beta 
         Beta_pos=Positions(i,:); 
     end 

     if fitness>Alpha_score && fitness>Beta_score && fitness<Delta_score  
         Delta_score=fitness; %  更新delta 
         Delta_pos=Positions(i,:); 
     end 
 end 

 a=2-l*((2)/Max_iter); %  线性下降从 2到0 

% 更新灰狼个体的位置

 for i=1:size(Positions,1) 
     for j=1:size(Positions,2)      

         r1=rand(); % r1  是 0 到 1 之间的随机数

         r2=rand(); % r2 是 0 到 1 之间的随机数


         A1=2*a*r1-a;  
         C1=2*r2;  

         D_alpha=abs(C1*Alpha_pos(j)-Positions(i,j));  
         X1=Alpha_pos(j)-A1*D_alpha;  

         r1=rand(); 
         r2=rand(); 

         A2=2*a*r1-a;  
         C2=2*r2;  

         D_beta=abs(C2*Beta_pos(j)-Positions(i,j));  
         X2=Beta_pos(j)-A2*D_beta;  

         r1=rand(); 
         r2=rand();  

         A3=2*a*r1-a;  
         C3=2*r2;  

         D_delta=abs(C3*Delta_pos(j)-Positions(i,j));  
         X3=Delta_pos(j)-A3*D_delta;  

         Positions(i,j)=(X1+X2+X3)/3; 

     end 
 end 
 l=l+1;     
 Convergence_curve(l)=Alpha_score; 

end

Answer 1

你这个是灰狼算法的代码吧，然后没有定义变量躯体是什么变量得查看清楚
