嗨，我有这段代码，它不断给我一个“索引超出矩阵尺寸”错误。我试图用“battery_capacity”矩阵=2的值来启动h=1、d=1、24“h”和3“d”的循环，但这似乎与矩阵大小相矛盾。任何帮助表示赞赏！“h-1”是否会导致问题。错误出现在第二次写入“battery_capacity”我的代码是针对 idx_number_panels = 1:length(number_panels) % range of PV panel units 检查

for number_turbines = 0:2 % range of wind turbine units examined
  for number_batteries = 1:50 % range of battery units examined
    for h=2:25 %# hours
      for d = 1:number_of_days %# which day
        battery_capacity(idx_number_panels, number_turbines+1, ...
                         number_batteries, 1, 1) =  2*number_batteries;
        %% Charging
        battery_charging(idx_number_panels, number_turbines+1, ...
                         number_batteries, h, d) ...
          = hourly_surplus(idx_number_panels, number_turbines+1, ...
                          number_batteries, h, d) ...
            + battery_capacity(idx_number_panels, number_turbines+1, ...
                               number_batteries, h-1,d);
    end
  end
end

调试器

error line 134 

battery_charging(idx_number_panels, number_turbines+1 ,number_batteries, h,d) =        hourly_surplus(idx_number_panels, number_turbines+1 ,number_batteries, h,d)...
    K>> sz = size(battery_charging)

sz =

K>> index = [idx_number_panels, number_turbines+1 ,number_batteries, h-1,d]

index =

K>> ndims(battery_charging)

在命令行中运行“battery_charging”

>> battery_charging

battery_charging(:,:,1,1) =

 0


battery_charging(:,:,1,2) =

  0

4

比试图从代码中找出问题所在更容易的是按如下方式进行调试。首先，将调试器设置为在出错时中断：

>> dbstop if error

现在，再次运行您的代码。当您遇到错误时，您应该会遇到调试提示：

K>>

您现在可以在出错时检查不同索引的值和矩阵的形状，并找出问题出在哪里。
