kml_fft(f)_execute_r2r

Execute the created FFT plan. However, kml_fft(f)_execute_r2r can accept new input and output data rather than the plan data as parameters.

C interface:

void kml_fft_execute_r2r(const kml_fft_plan p, double *in, double *out);

void kml_fftf_execute_r2r(const kml_fftf_plan p, float *in, float *out);

Fortran interface:

CALL KML_FFT_EXECUTE_R2R(P, IN, OUT);.

CALL KML_FFTF_EXECUTE_R2R(P, IN, OUT);

Parameter	Data Type	Description	Input/Output
p	Double precision: const kml_fft_plan Single precision: const kml_fftf_plan	FFT plan obtained by calling the plan function.	Input
in	Double precision: double* Single precision: float*	Inputs the data to be transformed.	Input
out	Double precision: double* Single precision: float*	Outputs the data generated using FFT.	Output

C: "kfft.h"

Fortran: "kfft.f03"
