sfft_exit, dfft_exit, cfft_exit, zfft_exit 

Final step for fast fourier transform in one dimension

FORMAT

  status = {S,D,C,Z}FFT_EXIT (fft_struct)

Arguments

  fft_struct          record /dxml_s_fft_structure/ for single-precision real
                      operations
                      record /dxml_d_fft_structure/ for double-precision real
                      operations
                      record /dxml_c_fft_structure/ for single-precision
                      complex operations
                      record /dxml_z_fft_structure/ for double-precision
                      complex operations
                      This argument must be included but it is not necessary
                      to modify it in any way. It refers to the data
                      structure that was specified by the initialization
                      step. See the CXML Reference Guide  for more
                      information on the data structure.

Description

  The _FFT_EXIT functions remove the internal data structures created in the
  _FFT_INIT functions.  These functions are the final step in a three-step
  procedure. They release the virtual memory that was allocated by the
  _FFT_INIT functions.

Return Values

  0                  DXML_SUCCESS()

  12                 DXML_INS_RES()
