[Octave-bug-tracker] [bug #43742] ifft, ifft2, ifftn should accept 'nonsymmetric' and 'symmetric' options

[Markus Mützel]

Follow-up Comment #13, bug #43742 (project octave):

I'm not sure if it makes sense to implement this flag in the way proposes
here.
Instead, it would probably be better to setup FFTW to use a planner from the
function `fftw_plan_many_dft_c2r` [1] or `fftw_plan_many_r2r` [2].

That should be done in liboctave probably around here:
