EXEC_FFTW Subroutine

public subroutine EXEC_FFTW(KTYPE, KRLEN, KCLEN, KOFF, KFIELDS, LD_ALL, PREEL)

@brief Execute FFTW transforms for arrays stored as PREEL(field,point).

Note

This routine shares the module-wide FFTW plan cache, so calls may serialize briefly in CREATE_PLAN_FFTW when accessing the FFTW_CREATE critical region.

Arguments

Type IntentOptional Attributes Name
integer(kind=JPIM), intent(in) :: KTYPE

Transform direction selector: 1 for complex-to-real and -1 for real-to-complex.
integer(kind=JPIM), intent(in) :: KRLEN

Number of real values in each transform.
integer(kind=JPIM), intent(in) :: KCLEN

Storage length of the packed FFT segment in real-valued form.
integer(kind=JPIM), intent(in) :: KOFF

One-based offset of the transform segment inside PREEL.
integer(kind=JPIM), intent(in) :: KFIELDS

Number of fields to transform.
logical, intent(in) :: LD_ALL

If true, execute all fields in one batched FFTW call; otherwise transform one field at a time.
real(kind=JPRB), intent(inout) :: PREEL(:,:)
