Question

我有一个值矩阵，如下所示。

candidate_edges =
   10.0000   10.0000    6.0000
  155.5000  105.5000   75.5000
   25.5000  105.5000   75.5000
  295.5000  415.5000  155.5000
  185.5000  415.5000  155.5000
  185.5000  485.5000  155.5000
  195.5000  305.5000   74.5000
  115.5000  305.5000   74.5000
  115.5000  395.5000   74.5000
  195.5000  395.5000   74.5000
   25.5000  185.5000   75.5000
  155.5000  185.5000   75.5000
  295.5000  415.5000    5.5000
  295.5000  415.5000  155.5000
  185.5000  415.5000  155.5000
  195.5000  305.5000    5.5000
  195.5000  305.5000   74.5000
  195.5000  395.5000   74.5000
  295.5000  415.5000    5.5000
  195.5000  395.5000    5.5000
  295.5000  485.5000    5.5000
  300.0000  600.0000         0
  295.5000  415.5000  155.5000
  185.5000  415.5000  155.5000

我想生成长度为1：length（candidate_edges）的数组，并且在每个单元格中，我想存储上述矩阵的每一行。以下是我的代码

cnode = zeros(1, n);
cnode = cell(1, n);
for k = 1:length(cnode)
    for j = 1:length(candidate_edges)
        cnode{k} = candidate_edges(j,:);
    end
end

在输出中，我在每个单元格中只得到相同的值。

Answer 1

您不需要两个循环。例如这应该做

cnode = cell(1, size(candidate_edges, 1))
for k = 1:numel(cnode)
    cnode{k} = candidate_edges(k,:);
end

Answer 2

你也可以使用内置的MATLAB函数//Function to Print the name of Next Day in Javascript var NextDay = (function () { counter = 0; var nextDay = function () { var days = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"]; var date = new Date(); var dayNumber = date.getDay() + counter; if (dayNumber < 6) { dayNumber = dayNumber; } else { dayNumber = (dayNumber % 6); } var dayName = days[dayNumber]; counter += 1; return dayName; }; return nextDay; })(); NextDay(); NextDay(); NextDay(); NextDay(); NextDay(); NextDay(); NextDay(); NextDay();，如下所示：
