sfft_exit_2d, dfft_exit_2d, cfft_exit_2d, zfft_exit_2d 

Final step for fast fourier transform in two dimensions

FORMAT

  status = {S,D,C,Z}FFT_EXIT_2D (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 created in the initialization step.

Description

  The _FFT_EXIT_2D functions remove the internal data structures created in
  the _FFT_INIT_2D functions.  These functions are the final step in a
  three-step procedure. They release the virtual memory that was allocated by
  the _FFT_INIT_2D functions.

Return Values

  0                  DXML_SUCCESS()

  12                 DXML_INS_RES()
