can anyone help me to run this code , thank you

for i=1:300
    for j=1:100
        A{i,j}=10*randn(2,8);
        B{i,j}=10*randn(2,8);
        MA{i,j}=mean(A{i,j},1);
        MB{i,j}=mean(B{i,j},1);
        [E{i,j}, idx{i,j}] = min([MA{i,j};MB{i,j}]); 
        AB{i,j} = nan(2, length(E{i,j})); 
        AB{i,j}(:,idx==1) = A{i,j}(:,idx==1); 
        AB{i,j}(:,idx==2) = B{i,j}(:,idx==2);
    end
end
