如何在matlab建立一个矩阵，矩阵每个元素都是结构体

比如一维的，A是结构体CodeGroup=[CodeGroup A]；
如果是CodeGroup是二维，三维的怎么办

---

CodeGroupA = struct;
CodeGroupB = struct;
CodeGroupC = struct;
CodeGroupD = struct;
CodeGroup = cell(2,2); % 用租或元胞数族型搏组实兆祥现
CodeGroup{1,1} = CodeGroupA;
CodeGroup{1,2} = CodeGroupB;
CodeGroup{2,1} = CodeGroupC;
CodeGroup{2,2} = CodeGroupD;
CodeGroup
CodeGroup =
[1x1 struct] [1x1 struct]
[1x1 struct] [1x1 struct]
