mirror_hermitian_fft R Documentation
Mirror a set of FFT values by assuming the fourier transform to be hermitian.
Description
The FT of a purely real function is hermitian. Exploit this to obtain a full
set of FFT values from the values at positive frequencies only (and f=0).
Usage
mirror_hermitian_fft(fft_vals, sampling)
Arguments
fft_vals
A complex vector containing the FFT values of a function for
the frequencies given by sampling$freqs_to_calc (i.e. f=0 as well as the
positive ones).
sampling
A sampling object, as usually created by
create.sampling.
Value
A complex vector containing the full set of FFT values at all
frequencies (and in the same order as) given by sampling$fft_freqs.
Note
Should be clear, but once again: This function produces false results
but **does not throw an error** if the underlying function is not purely
real!
