matlab的排序，谢谢

matlab的排序，比如：i    t   y
1  4   0.1
1  5   0.3
1  6   0.5
2  4   0.2
2  5   0.4
2  6   0.8

...
修改为
i    t   y
1  4  0.1
2  4  0.2
1  5  0.3
2  5  0.4
1  6  0.5
2  6  0.8

请问上述panel data数据集在MATLAB中如何相互转换，敬请给出程序，谢谢

sortrows(Data,[2,3])

if Data is a matrix. [2 3] refers to the second column and the third column.
