M=input('Enter number of manufacturers'); D=input('Enter number of distributers'); O=1; T=1; R=1; Z=1; for m=1:M; for d=1:D; Cmd=zeros(M:D); Cmd(m,d)=input('Enter traveling cost for manufacturer to distributer'); disp(Cmd); end end

You're overwriting the matrix Cmd every iteration because of the line Cmd=zeros(M:D). Take it outside of both for loops.
M=input('Enter number of manufacturers: ');
D=input('Enter number of distributers: ');
O=1; T=1; R=1; Z=1;
Cmd=zeros(M:D);
for m=1:M
for d=1:D
Cmd(m,d)=input('Enter traveling cost for manufacturer to distributer: ');
disp(Cmd);
end
end
To sum over all the elements of the matrix you can use sum(Cmd(:)).

O=1 for u=1:U; Cuo=zeros(u:O); Cuo(u,O)=input('Enter traveling cost for retailer to collection center'); end SumCuo=Sum(Cuo(:)); disp(SumCuo);
