FourierDST

• Possible types of discrete sine transform for a list of length giving a result are:

• 1.	DST-I
  2.	DST-II
  3.	DST-III
  4.	DST-IV

• FourierDST[list] is equivalent to FourierDST[list, 2].

• The inverse discrete sine transforms for types 1, 2, 3, 4 are types 1, 3, 2, 4, respectively.

• The list given in FourierDST[list] can be nested to represent an array of data in any number of dimensions.

• The array of data must be rectangular.

• If the elements of list are exact numbers, FourierDST begins by applying N to them.

• FourierDST can be used on SparseArray objects.
