FourierDST

FourierDST[list]
finds the Fourier discrete sine transform of a list of real numbers.
FourierDST[list, m]
finds the Fourier discrete sine transform of type m.
  • Possible types m of discrete sine transform for a list u_r of length n giving a result v_s are:
  • 1.DST-I
    2.DST-II
    3.DST-III
    4.DST-IV
  • 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.
