在matlab中从单元格数组创建直方图

Question

我已经在matlab中完成了547个点的最近邻居程序，并且我得到了一个大小为＆lt; 547x1 cell＆gt;的单元格阵列。这是数据：

Cell array =

数据描述了每个粒子我有多少邻居，我想要做的是用直方图表示这个数据，以便人们可以很容易地看到我有多少次6个neihbours多少次4,5,7,8。 ..如果有人可以帮助建议一种在直方图中表示和量化这些数据的方法，我很难在两行之间进行阅读，看看有多少6或X数我感激

编辑：回答下面的百分比生成直方图。

我用以下方式绘制了直方图：

          [nelements,centers]=hist(cellfun(@numel,S));
          numNeighbors = cellfun(@numel,S);
          [nelements,centers]=hist(numNeighbors,unique(numNeighbors))
          pcts = 100 * nelements / sum(nelements)
          figure
          bar(centers,pcts)

在y轴上显示每个x值出现的百分比，现在可以显示直方图上的百分比数字，如上图所示，这样可以很容易地看到数字???

假设您的单元格数组为C，然后尝试hist(cellfun(@numel,C))。为了更好地展示，可能：

numNeighbors = cellfun(@numel,C);
hist(numNeighbors,unique(numNeighbors))
