6.40.19  Sorting a list by increasing order: SortA

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

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

Examples.

• Input:
  SortA([3,4,2])
  Output:

  ⎡ ⎣

  2,3,4

  ⎤ ⎦

• Input:
  SortA([[3,4,2],[6,4,5]])
  Output:

  ⎡ ⎢ ⎣

  2 3 4 5 6 4

  ⎤ ⎥ ⎦
