我首先抄了几个.m文件
function pop = TSPdecode (Popsize , ,Chrom ,W)
for i = 1 :Popsize
tempW = W ;
for j = 1 :
pop ( i , j) = tempW (chrom( i , j) ) ;
for k = (Chrom( i , j) ) : ( －j)
tempW( k) = tempW( k + 1)
end
end
end
function rpop = rotatepop (pop, Popsize, )
for i = 1 :Popsize
rpop = [pop ( i ,2 : ) ,pop ( i ,1) ]
end
function cost = TSPcost (Popsize , pop ,rpop)
for i = 1 :Popsiz
cost ( i) = Sum (diag ( D (pop ( i ,
‘) , (pop ( i ,
‘) ) )
end
然后在command windows中输入了
Popsize=10;Ncities=5;
D = [0 6 18 4 8 ; 7 0 17 3 7 ; 4 4 0 4 5 ; 20 19 24 0 22 ; 8 8 16 6 0];
cost = TSPcost (Popsize, pop, rpop);
出错
：??? Undefined command/function 'D'.
Error in ==> TSPcost at 3
cost(i)=sum(diag(D(pop(i,'),(pop(i,')))
有劳大虾们！谢谢
