结构中的八度结构

Question

我想在 Octave 的结构中创建结构。看起来像

class =
    {
        grade = Graduate
        studentname = John
        university =  St. Jones
        student=
             {
                 name=John
                 age=18
                 address=Houston
             }

   }

为了在我写下的结构中实现这个结构

>> class.grade='graduate';
>> class.studentname='John';
>> class.university='St.Jones';

>> student.name='John';
>> student.age=18;
>> student.address='Houston';

>>student.class=struct %To create structure within a structure

我得到了这个输出：

student =

scalar structure containing the fields:

name = John
age =  18
address = Houstan
class =

  scalar structure containing the fields:

我不明白为什么class结构在这里是空的？如果我尝试运行这样的代码也是如此

>> class.student=struct

输出为

class =

  scalar structure containing the fields:

grade = graduate
studentname = John
university = St.Jones
student =

  scalar structure containing the fields:

请帮我解决问题。

所以，从我的角度来看，有两种可能。

要么设置您的（子）结构 student，然后再设置 class.student = student。通过这种方式，class 中的字段 student 隐含地成为一个（子）结构。代码将是这样的：

class.grade = 'graduate';
class.studentname = 'John';
class.university = 'St.Jones';

student.name = 'John';
student.age = 18;
student.address = 'Houston';

class.student = student

        class =

          scalar structure containing the fields:

            grade = graduate
            studentname = John
            university = St.Jones
            student =

              scalar structure containing the fields:

                name = John
                age =  18
                address = Houston

或者您可以在开始时使用嵌套结构，如下所示：

class.grade = 'graduate';
class.studentname = 'John';
class.university = 'St.Jones';

class.student.name = 'John';
class.student.age = 18;
class.student.address = 'Houston';

class

        class =

          scalar structure containing the fields:

            grade = graduate
            studentname = John
            university = St.Jones
            student =

              scalar structure containing the fields:

                name = John
                age =  18
                address = Houston

同样，class 中的字段 student 也隐含地成为一个（子）结构。

希望对您有所帮助！
