6.40.20  Sorting a list by decreasing order: SortD

The SortD command sorts a list or a matrix in decreasing order.

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

Examples.

• Input:
  SortD([3,4,2])
  Output:

  ⎡ ⎣

  4,3,2

  ⎤ ⎦

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

  ⎡ ⎢ ⎣

  4 3 2 4 6 5

  ⎤ ⎥ ⎦
