不好意思，今天在寫這段時一直沒辦法解決；所以想請各位高手幫忙我看一下問題在哪邊 ><" function new_popu=ga_operator (init_popu,popu_fit,n,xover_rate) %selection counter=0; for z=1:n/2 parent1=0; parent2=0; new_popu=[]; x =rand(); y =rand(); check_point1 = 0 popu_fit_sum = cumsum(popu_fit) xover_point = 3; for i=1:n surv_rate = popu_fit_sum(i) / sum(popu_fit) check_point1 = x / sum(popu_fit) while check_point1 < surv_rate check_point1 = check_point1+1 end if (check_point1 < surv_rate) temp1 = init_popu(i,:) parent1=temp1 break; end end check_point1 = 0 for i=1:n surv_rate = popu_fit_sum(i) / sum(popu_fit) check_point1 = x / sum(popu_fit) while check_point1 < surv_rate check_point1 = check_point1+1 end if (check_point1 < surv_rate) temp2 = init_popu(i,:) parent2=temp2 break; end end check_point1 = 0 %crossover if rand > xover_rate new_popu(z*2-1,:)=[parent1(1:xover_point) parent2(xover_point+1:6)] new_popu(z*2,:)=[parent2(1:xover_point) parent1(xover_point+1:6)] else new_popu(z*2,:)=[parent1] new_popu(z*2-1,:)=[parent2] end end 然後執行時跑出這段錯誤 ??? Index exceeds matrix dimensions. Error in ==> ga_operator at 65 new_popu(z*2,:)=[parent2(1:xover_point) parent1(xover_point+1:6)] 請問一下，我的語法或邏輯上哪邊出問題？能不能給我個提示幫忙一下，感激不盡! -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.126.143.29
