If I define 's1' as follows( i dont know Is it correct to define 's ' as a three-dimensional matrix?)

max_iteration=5;
a=zeros(10,48);
b=zeros(10,48);
for k=1:max_iteration
    for i=1:10
        s(k,i,:)=(a(i,:)-b(i,:);
    end
 

Now, I want to find out "s" value , for example in iteration 4 . I mean how i can findout in intration4 , value s_new(:,:) which is 2d matrix with size 10*48 ?

itr1 : s1

itr2 : s2

itr3 : s3

itr4 : s4

itr5 : s5

which s1,s2,s3,s4,s5 should be 10*48

在 MATLAB Online 中打开

max_iteration=5;
a=zeros(10,48);
b=zeros(10,48);
s = zeros(10,48,max_iteration);
for k=1:max_iteration
    % presumably a and/or b change on each iteration
    s(:,:,k) = a-b;
end
