How to connect all result?

Hello guys,I'm very new in matlab.

I have some problem about for loop it show result just only the lastest calculation so how should i do to show all result in one tine

for i=0:bond(860)           %bond is data that include 860*2 table
    a=[bond(i+1,:)];
    B=[repmat(a(1),[length(nonzeros(a))-1 1]) nonzeros(a(2:end)')]   
    
end

%I just want to connect all result together thank you.

Use cell array to store the vectors

B=cell(1,bond(860)+1)
for i=1:bond(860)+1           %bond is data that include 860*2 table
    a=[bond(i+1,:)];
    B{i}=[repmat(a(1),[length(nonzeros(a))-1 1]) nonzeros(a(2:end)')]   
end
B

Also see cell2mat function (If Needed)
