Name

sfft_exit_3d, dfft_exit_3d, cfft_exit_3d, zfft_exit_3d − Final step for fast fourier transfrom in three dimension

FORMAT

status = {S,D,C,Z}FFT_EXIT_3D (fft_struct)

Arguments

fft_structrecord /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_3D functions remove the internal data structures created in the _FFT_INIT_3D functions.  These functions are the final step in a three-step procedure. They release the virtual memory that was allocated by the _FFT_INIT_3D functions. 

Return Values

0DXML$_SUCCESS()

12DXML$_INS_RES()
