在Matlab r2017b中创建嵌套或分层索引表

% 创建一个包含嵌套表的表格
data = {'John', 25, [80, 90, 85]; 'Emily', 28, [75, 95, 80]};
nestedTable = table(data(:, 1), data(:, 2), data(:, 3), 'VariableNames', {'Name', 'Age', 'Grades'});

% 在嵌套表中添加更多的行
newData = {'Mike', 30, [90, 85, 95]; 'Sarah', 27, [85, 80, 90]};
newNestedTable = table(newData(:, 1), newData(:, 2), newData(:, 3), 'VariableNames', {'Name', 'Age', 'Grades'});
nestedTable = [nestedTable; newNestedTable];

% 访问嵌套表中的数据
name = nestedTable.Name{1};
age = nestedTable.Age{2};
grades = nestedTable.Grades{3};

% 显示整个嵌套索引表
disp(nestedTable);

% 创建一个具有分层索引的表格
data = [80, 90, 85; 75, 95, 80; 90, 85, 95; 85, 80, 90];
rowIndex = {'John', 'John', 'Emily', 'Emily'};
colIndex = {'Math', 'Physics', 'Chemistry'};
hierarchicalTable = table(data, 'RowNames', rowIndex, 'VariableNames', colIndex);

% 访问分层索引表中的数据
mathGrade = hierarchicalTable{'John', 'Math'};
physicsGrades = hierarchicalTable{'John', 'Physics', 'Emily', 'Physics'};

% 显示整个分层索引表
disp(hierarchicalTable);
