赋值具有比非单例更多的非单例rhs维度

Question

您好，我对此代码行有疑问我是一名matlab新手，我只想尝试获取非方阵矩阵的所有条目。

 X=double(imread(I));
 Y=zeros(size(X,1),size(X,2));
 Ie=zeros(1,256);
 h = calchisto(I);
 [~ , b]= max(h);
 [~ , c]= max(max(X));
 [~ , d]= min(min(X));
 size(X,1)
 size(X,2)
 for i = 1 : size(X,1)
    for j = 1 : size(X,2)
        Y(i,j)=(b-1)*((X(i,j)-d)./(c-d));
        Ie(1,abs(floor(Y(i,j)+1)))=Ie(1,abs(floor(Y(i,j)+1)))+1;
    end
 end
