谁有弗洛伊德算法的Matlab程序啊?

答案：For  i:=1  to vtxnum do
  for  j:=1  to  vtxnum  do
     begin  length[i,j]:=cost[i,j];
              if  length[i,j]<max then path[i,j]:=[i]+[j];  
     end;
For  k:=1 to vtxnum do
  for  i:=1  to  vtxnum  do
     for  j:=1 to vtxnum  do
        if  length[i,k]+length[k,j]<length[i,j]  then 
         begin  length[i,j]:=length[i,k]+length[k,j];
                   path[i,j]:=path[i,k]+path[k,j];
         end;
