What's wrong in this code? why is this not displaying whole matrix?and how to sum whole matrix?

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);
