Fill an array over an iteration

Given the following code

 D= [1 2 3  ; 4 5 6 ]
 
 for i= 1: size(D,1)
 M = [4 2 4 3 2; 2 1 3 1 2; 4 1 2 3 1];
 r= size(M,1)
 c=size(M,2)
 Tc=cumsum(M)
 T=cumsum(Tc,2)
 
 %T= [4 6 10 13 15; 6 0 0 0 0 ; 10 0 0 0 0]

 for j= 2:size(T,1)
     for k= 2:size(T,2)
         T(j,k)=max(T(j,k-1)+M(j,k),T(j-1,k)+M(j,k))      
     end
 end
 
 rowNum = find(any(T >18,2),1,'first');
 B=D(i,:);
 Dstop=B(1:rowNum-1)
 BBB(i,:)=B(:)  %% HERE THE PROBLEM
 end
 

I have a problem in the penultime row, where I want to fill the vector BBB with the value Dstop that I obtain at each cycle

does someone may help me?

Does using

BBB(i,:)=Dstop

instead of

BBB(i,:)=B(:)

do what you want?

If not, you need to explain a bit more.
