Output

These functions use the following arguments for output:

• a - S3L array handle for a parallel real array. Upon successful completion, S3L_rc_fft overwrites a with the packed representation of the complex result of the forward FFT. S3L_cr_fft overwrites a with the real result of the inverse FFT.

• ier (Fortran only) - When called from a Fortran program, ese functions return error status in ier.
