6.3.18  Sorting a list by increasing order

The SortA command sorts a list or a matrix in increasing order.

• SortA takes L, a list.
• If L is not a matrix, then SortA(L) returns a copy of L with the elements in increasing order (if L is not a matrix).
• If L is a matrix, then SortA(L) returns a copy of L with columns sorted according to increasing order in the first row.
