Hi all,

I understand that ‘symmetric’ in ifft2 assumes data is conjugate symmetric and will output real values, but I want to know how exactly is this done. Specifically:
with ‘symmetric’, will only half of the data be used or still the whole matrix is used, but just output real values?
if x is not conjugate symmetric but I still pass in ‘symmetric’, what will happen?
Thanks in advance.Hi all,
