Excel中有按某一列排序，同時擴展到其他列，Matlab中對應的有sortrows:
The MATLAB function sortrows(A,j) sorts the rows of the matrix a based on the entries of the j-th column. For example, enter the following in MATLAB:
A = [1 2 3
3 0 9
6 5 4]
B = sortrows(A,2)
C = sortrows(A,3)
You will receive the following output:
B = 3 0 9
1 2 3
6 5 4
C = 1 2 3
6 5 4
3 0 9
