MATLAB: Sorting Vectors descending order

sorting vector descending order

I appreciate if anyone could help me for writing below sorting for different vectors: Assumed :
A1= (a1,a2)
A2= (a3,a4)
A3=(a5,a6)
.
.
An= (ai, aj)
How can I sort A1, A2, … ,An. by just first member comparison descending order (1) or second comparison (2), or both member comparison (3): solution : (for example)
1)  a3>a1>a5 ---> output: A2, A1, A5...
or
2) a6>a4>a2 ----> output:  A3,A2,A1
3) a1>a3 >a5 and a2>a4 >a6  --->output: A1, A2,A3

The sortrows function is probably what you want. See specifically Sort Rows of a Matrix
